A plane glass is placed over a various coloured letters (violet, green, yellow, red) The letter which appears to be raised more is,

A

red

B

yellow

C

green

D

violet

Text Solution

Verified by Experts

Letters appear to be raised depending upon the refractive index of the material. Since violet has a higher refractive index than red (the index increases with frequency), red will be the lowermost.

The refractive index of a material changes by 0.014 as the colour of the light changes from red to violet. A rectangular slab of height 2.00 cm made of this material is placed on a newspaper. When viewed normally in yellow light, the letters appear 1.32 cm below the top surface of the slab. Calculate the dispersive power of the material.

Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?

A glass slab (mu = 1.5) of thickness 6 cm is placed over a paper. What is the shift in the letters?

A printed page is kept pressed to a glass cube (mu=1.5) of edge 6.0 cm. By what amount will the printed letters appear to the shifted when viewed from the top?

Read the passage and Answer the following question: In, vacuum the velocity of light radiation with different wavelength is the same. But in a material medium, the velocity of different colour radiations is not the same and they travel with different paths. Due to this, the refractive index of the medium is different for different colours. If white beam of light is incident on a glass prism, the angle of refraction for different colours is different. When Sunlight is incident on a refracting surface, then it gets split into seven coloured spectrum and emerges out. The splitting of light into its component colours is called dispersion. Sir Isaac Newton was the first to use a glass prism to obtain the spectrum of Sunlight. A glass prism is transparent medium bounded by two plane surfaces inclined at an angle. When white light is dispersed into seven colours by a prism, different colours of light bend through different angles with respect to incident ray. Out of these seven colours, red light bends the least, while violet light bends the most. So, the rays of each colour emerge along different paths and becomes distinct. Hence, we get spectrum of seven - different colours. Q. How do emergent rays appear ?
