1.	A light ray of yellow colour is incident on an equilateral glass prism at an angle of incidence equalto 48° and suffers minimum deviation by an angle of36º. (i) What will be the angle of emergence ?(ii) If the angle of incidence is changed to (a) 30°,(b) 60°, state in each case whether the angle ofdeviation will be equal to, less than or more than36° ?
Answer» I hope it will helpful to you and plss thankful to me plzzzzExplanation::i As the RAY is SUFFERING minimum deviation in an equilateral glass prism soi1 = i2 ∴ i2 = 48o ii If the angle of incidence is CHANGED TOA 30o the angle of deviation will be more than 36o.b 60o the angle of deviation will be more than 36o.
