An achromatic prism is made by crown glass prism `(A_(c) = 19^(@))` and flint glass prism `(A_(F) = 6^(@))` . If `.^(C)mu_(y) = 1.5` and `.^(F)mu_(v) = 1.66`, then resultant deviation for red coloured ray will be

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

An achromatic prism is made by combining two prisms P_(1)(mu_(v)=1.523,mu_(r)=1.515) and P_(2)(mu_(v)=1.666,mu_(r)=1.650) Where mu represents the refractive index if the angle of the prism P_(1) is 10^(@) then the angle of the prism P will be
