Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
If the index of refraction is less than the index of incidence, which of the following is TRUE?
a.The refracted ray bends towards the normal
b.Angle of refraction is equal to the angle of incidence
c.Angle of refraction is larger than the angle of incidence
d.Angle of refraction is smaller than the angle of incidence
Which of the following is TRUE?
a.Increasing the incident angle has no effect on the intensity of the reflected light ray.
b.Increasing the incident angle decreases the intensity of the reflected light ray.
c.Increasing the incident angle increases the intensity of the refracted light ray.
d. Increasing the incident angle increases the intensity of the reflected light ray.
