Refraction of Light
To find a relationship between the angles of incidence and the angles
of refraction by obtaining a set of readings for the angles of
incidence and refraction as a light ray passes from air into perspex.
Refraction is the bending of a wave when it enters a medium where it's
speed is different. The refraction of light when it passes from a fast
medium to a slow medium bends the light ray toward the normal to the
boundary between the two media. The amount of bending depends on the
indices of refraction of the two media and is described quantitatively
by Snell's Law. (Refer to diagram below)

Subject: The Angel of Light
“Even Satan disguises himself as an angel of light. So it is no surprise if his servants, also, disguise themselves as servants of righteousness” (vv. 14–15a).
- 2 Corinthians 11:14–15
Second Corinthians 11:14–15 contains perhaps the most important bit of information all believers need to remember concerning the nature of Satan and his work. Paul tells us in today’s passage that the Devil “disguises himself as an angel of light” (v. 14). Of course, Satan and his minions are often the direct source of much of the outright perversity and evil that we see on this planet. However, since he is the “father of lies” (John 8:44), the Evil One would much rather

To investigate whether light intensity of incoherent lights varies inversely with the square of the distance holds true in real-life situations and under laboratory conditions. Techniques utilised in the experiment included measuring the distance from the light source to the light sensor, recording the light intensity of a light source and recording observations with accuracy. The light from the light source that passes through the cardboard cylinder tube changes as the distance from the light sensor increases. The results show that light intensity of incoherent lights varies inversely with the square of the distance in real-life situations and under laboratory conditions

Ways to Light Up Your Home
We've all been in rooms that just feel good. They have a palpable, comfortable atmosphere that makes you want to put up your feet and stay a while. Beyond the practicality of light, which is that we need it to see, the lighting scheme in your home has a big influence on the personality of a room. You wouldn't want a bright overhead light shining down on an intimate dinner party or a single lamp lighting a space where you're trying to do a project. The main goal of lighting design is to introduce varying degrees of light into a room, which are called layers. If you only have direct light sources, it will make a space feel dark and gloomy. And if you light the

The Effect of Light on Photosynthesis
Plants need and use the same light of foods as animals but while
animals have to eat other things to get their food, plants make it
themselves. The way they do this is called photosynthesis. The other
ways that plants are different from animals, such as having leaves and
root or being green, they are all linked with photosynthesis. In
photosynthesis, plants take carbon dioxide from the air and water from
the soil, and use the energy from the sunlight to convert them into
food. The first food they make is glucose but that can later be
changed into other food types. The sunlight is absorbed by the green

THROUGH EDUCATION OUR MOTHERLAND RECEIVES LIGHT
The vital breath of prudent Education
Instills a virtue of enchanting power;
She lifts the motherland to highest station
And endless dazzling glories on her shower.
And as the zephyr's gentle exhalation
Revives the matrix of the fragrant flower,
So education multiplies her gifts of grace;
With prudent hand imparts them to the human race.
For her a mortal-man will gladly part
With all he has; will give his calm repose;
For her are born all science and all art,
That brows of men with laurel fair enclose.
As from the towering mountain's lofty heart
The purest current of the streamlet flows,

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
August 20, 2001
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the University of Surrey, might enable this type of light, which is dark blue in colour, to be used to adjust the body clocks of shift workers, those affected by seasonal affective disorder (SAD) or of travellers on long haul flights to avoid jet lag.

In this experiment, we tested the Armadillidium’s ability to recognize differences in light and dark environments using concepts of behavioral ecology. We hypothesized that the Armadillidium would indeed recognize this difference and would also prefer darker regions. After running ten experimental trials, we found that there was no statistical significance to our findings. However, the gross data does show that the crustaceans spent 67% of their time in the dark regions. Published data concurs with this finding. We suggest a greater sample size for more accurate statistical results in future experiments.

The symbols used in the setting are especially vital to the reader's interpretation of the story. Many of the obvious symbols, the hills, the white elephant, and the terrain, allow the reader to interpret the story in different ways. Following the first reading, one assumes the couple continued their trip to Madrid for the abortion and soon after separated; however, after many readings a reader may not believe that to be the case.Hemingway begins the story by describing the surrounding landscape of

How is battle represented in the Charge Of The Light Brigade and Henry V?
The poem Charge of the Light Brigade, written by Alfred Lord Tennyson, is based on the battle of Balaclava which took place on the 25th October 1854 in the Crimean war. Act 4 Scene 3 of the Shakespearean play, â€œHenry Vâ€, contains a speech which King Henry V gave to inspire and motivate his soldiers before they go to fight in the battle of Agincourt which took place in France 441 years earlier, Friday 25th October, 1415. Both the poem and the speech are about war, courage and honour.
Tennyson uses language to show that battle is horrifying experience yet an honour. This is shown in the quote.â€ Stormâ€™d

TAKE CRIME AS A SOCIAL FENOMENON IN THE LIGHT OF MARXIST UNDERSTANDING.
The crime or exactly the criminal, according to Marx, was a stimulating subject for the development of productive forces and, simultaneously, a hero transgressor of bourgeois legal order. The Marxist approach could be cynical and offensive, especially to the hundreds of thousands of victims of violence. But we should not forget that Marx, in addition to a critic of capitalism, was a narrator of his reality. A narrator, romantic, that is, always attentive to modern drama.
Karl Marx interpreted the role of the criminal as an active element in the rational societies. The criminal activity is a force that regulates

Refraction is what happens to light when it passes from one medium to another. For example, things appear differently from the bottom of a swimming pool than on the top. Simplistically, refraction is the bending of light. The explanation for this phenomenon, however, can be described with light as rays and light as waves. No matter the case, it is important to remember that the speed of light is constant in every homogeneous medium, regardless of shape, size or form.

There are a few conditions required for photosynthesis to take place. They are: Chlorophyll, Light, Carbon Dioxide and Water. Each of these factors has a different effect on the rate of photosynthesis. In plants, the chlorophyll present in the chloroplasts, converts the light energy from the sun and converts it into chemical energy. It also traps the sun's light energy. Hence, the light is obtained from the sun, but an artificial source, e.g.: light bulb can be used. When carbon dioxide and water react
