1.	The refractive index of glass is 1.520 for red light and 1.525 for blue light. Let D_1 and D_2 are the angles of minimum deviation for red and blue respectively in a prism of the glass. Then
Answer» `D_1 lt D_2` `D_1 gt D_2` `D_1=D_2` `D_1` can LESS than or greater than DEPENDENT upon the ANGLE of prism. Answer :A
