Properties of Light. Light is a form of energy that causes the sensation of vision. Different theories on the nature of light were proposed on the basis of the fact that energy can be transferred from one point to another, either by particle motion or by wave motion.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Many known properties of light could be explained easily by a particle model. For example, it was known that when light reflects from a smooth surface, the angle of incidence is equal to the angle of reflection.

With higher refractive index, light ray is refracted more when it enters the glass block → Smaller angle of refraction and larger angle of incidence at B (inside block) that is greater than critical angle → Total internal reflection.
