CBSE Class 10 Answered

Dear student,

he amount of overall refraction caused by the passage of a light ray through a prism is often expressed in terms of the angle of deviation ().Because of the different indices of refraction for the different wavelengths of visible light, the angle of deviation varies with . Colors of the visible light spectrum which have shorter wavelengths (BIV) will deviated more from their original path than the colors with longer wavelengths (ROY).

Hope this helps.
