Question

1. The index of refraction is defined as the ratio of the speed of light in vacuum and the velocity of light in the medium of propagation rue b) False 2. The wavelength inside of a material with index of refraction larger than 1 is the same as in vacuum a) True b) False 3. The equation that relates the wavelength inside of a material (n2, A2) and the wavelength in vacuum (n1, ) is :2 = n2. Please determine veracity of following statement "n2 ni means that the wavelength is smaller in the material of propagation" b) False vacuum (n1, .) is :2-nA1. Please determine veracity of following statement: rue 4. The equation that relates the wavelength inside of a material (n2, A2) and the wavelength in "n2

Explanation / Answer

5)1)

True

Reason : The definition of refractive index is velocity of light in vacuum to the velocity of light in given medium

2)

False

Reason : As colour of light remain the same and colour depends on the frequency , so frequency remain the same and wavelength do changes

3)

True

Reason : refractive index is the ratio of speed of light in vacuum to the speed of light in given medium, speed of light in medium is the wavelength times the frequency , so it is inversely proportional. So it is true

4)

True

5)

False

Reason : Refractive index is different for different colour
