A light ray of yellow colour is incident on an equilateral glass prism at an angel of incidence equal to 48° and suffers minimum deviation by an angle of 36°.
- What will be the angle of emergence?
- If the angle of incidence is changes to (a) 30°, (b) 60°, state whether the angle of deviation will be equal to, less than or more than 36°?
Which of the two prism, A made of crown glass and B made of flint glass, deviates a ray of light more?
How does the angle of deviation depend on the refracting angle of the prism?
