refraction of light

Name the factors that affect the lateral displacement of light as it passes through a rectangular glass slab.

• thickness of block

• angle of incidence

• refractive index of glass

• wavelenght of light

The speed of light in glass is 2 × 10⁵ km/s. What is the refractive index of glass?

• 2 / 3

• 1.5

• 3 / 2

Name the subjective property of light related to its wavelength.

• refractive index

• frequency

• colour

• velocity

Jatin puts a pencil into a glass container having water and is surprised to see the pencil bend.Name the phenomenon responsible for the change.

• Reflection of light

• Refraction of light

• total internal reflection of light

• partial reflection and partial refraction

A monochromatic beam of light of wavelength λ passes from air into a glass block. choose the correct relation.

• v = c / λ

• v = λ / λ'

• μ = c / v

• λ / λ' = μ

As the ray of light passes from air to glass, state how the wavelength of light changes.

• wavelength increases

• wavelength decreases

• wavelength remains constant

• wavelength decreases and then increases

A boy uses blue colour of light to find the refractive index of glass. He then repeats the experiment using red colour of light.How will the refractive index of glass be ?

• the same

• μ decreases

• μ increases

• same as speed of light

Relation between wavelength and refractive index.

• μ_violet > μ_red

• μ_violet < μ_red

• μ_violet = μ_red

• μ has no relation with λ

• δ inversly proportional to μ

• δ equal to μ

• δ has no relation to μ

What is the dependence of angle of deviation on the wavelength of light ?

• δ is inversly proportional to λ

• δ is equall to λ

• δ is not relatedto λ
