PROPERTIES OF LIGHT. PROPERTIES OF LIGHT. Light like all waves can be reflected at a boundary between two media. This phenomena is simply called REFLECTION Light can also be transmitted from one medium to another. This phenomena is called REFRACTION. REFLECTION OF LIGHT.

THIS VIDEO SHOWS HOW A BEAMS OF LIGHT ARE REFLECTED FROM A MIRROR
YOU CAN GET BOTH SPECULAR AND DIFFUSE REFLECTION FROM A SURFACE.
SPECULAR REFLECTION FROM A ROUGH SURFACE
OPTICAL DEVICES HAVE HAD A TREMENDOUS EFFECT ON THE EVOLUTION OF OUR CIVILIZATION.
LIGHT RAYS CAN BE DIRECTED VIA REFLECTION TO FORM IMAGES.
IF THE IMAGE IS ON THE SAME SIDE OF THE MIRROR AS THE OBJECT, IT IS SAID TO BE “REAL” SINCE THERE WILL BE LIGHT AT ITS LOCATION.
SURENDRANATH HAS SIMULATIONS ON HIS CD THAT SHOW HOW IMAGES ARE FORMED BY CONVEX AND CONCAVE MIRRORS.
The change in the direction of travel due to a change in speed of the wave.
A PENCIL IN A GLASS OF WATER.
THE DIRECTION OF TRAVEL OF A TOY CAR IS AFFECTED AS IT TRAVELS ACROSS CARPET.
The angle of incidence or refraction is smaller in the medium in which the speed of light is slower.
This is usually a more dense medium.
SURENDRANATH HAS SIMULATIONS ON HIS CD THAT SHOW HOW LIGHT WAVES ARE REFRACTED AS THEY TRAVEL FROM AIR INTO A DENSE MEDIUM. NOTICE THAT THE WAVES TRAVEL SLOWER IN THE MORE DENSE MATERIAL.
THIS VIDEO SHOWS HOW A LIGHT BEAM IS REFRACTED THROUGH A LARGER ANGLE AS THE ANGLE OF THEN PRISM INCREASES.
Hold a lens in front of your eye. Ask the kids if your eye looks larger or smaller.
Which type lens makes your eye look larger?
Which type lens makes your eye look smaller?
THE REFRACTION OF DIFFERENT WAVELENGTHS DUE TO THE FACT THAT THEY TRAVEL AT DIFFERENT SPEEDS THROUGH LIGHT MEDIA.
SURENDRANATH HAS SIMULATIONS ON HIS CD THAT SHOW HOW LIGHT WAVES ARE REFRACTED BY RAINDROPS TO PRODUCE A RAINBOW.
DISPERSION CAUSES THE COLORS TO REFRACT AT DIFFERENT ANGLES.
