Question

A ray of light bends while passing from one transparent medium to another medium having a different refractive index. a) Name the phenomenon. Give reason for it. b) How do the following quantities change: speed, wavelength, frequency and amplitude if second medium is denser than the first medium? c) State whether the ray of light will bend or not if both the media have the same refractive index

Answer 1

Answer:

refraction is the phenomenon

speed ,wavelength , frequency and amplitude changes because when light passes from one rareer medium to a denser mediumit bends towards normal

Explanation:

if both media have same refractive index their will no refraction

Answer 2

Answer:

a) Refraction

Refraction is the bending of light when it travels from one medium to another medium. When light crosses the boundary between both of the mediums, then there is a deviation that occurs in the path of the light ray. This phenomenon is known as refraction.

b)speed ,wavelength , frequency and amplitude will change because when light passes from one rarer medium to a denser medium it bends towards normal

c)It will not bend because,

Refractive index is not the same at every wavelength. In addition, it can vary due to environmental conditions such as temperature and pressure, and even light intensity. If the index is exactly the same for two materials at some wavelength, then their refraction behavior at that wavelength will be exactly the same.
