Which of the two prism, A made of crown glass and B made of flint glass, deviates a ray of light more?

(a) The relation between speed of light in air c and in glass v is given by c/v = =1.5 (b) The wavelength of light in glass (λ1) μ = λ/λ1 = λ/1.5

(i) i2 = i1 (ii) Angle of deviation is minimum Explanation: In minimum deviation position, the refracted ray inside the prism travels parallel to it if the prism is equilateral and the...

(i) As the ray is suffering minimum deviation in an equilateral glass prism so i1 = i2  ∴ i2 = 48o  (ii) If the angle of incidence is changed to (a) 30o, the angle of...

(a) If the incident ray normal to prism then angle of incidence is 0o. (b) In this case the angle of refraction from the first face r1 = 0o. (c) As the...

The light ray bends at both the surfaces of prism towards its base.

The deviation produced by the prism does not depend on the size of prism.

(a) Violet, Indigo, Blue, Green, Yellow, Orange, Red. (b) No, different colours have different widths in the spectrum. (c) (i) Violet colour is deviated the most. (ii) Red colour is deviated the...

Both deviation and dispersion. Hint: When a white light ray falls on the first surface of a prism, light rays of different colours due to their different speeds in glass get...

The colour of the extreme end opposite to the base of the prism is red. Hint: The angle of deviation decreases with the increase in wavelength of light for a given...
