A combination of two prisms,one of flint and other of crown glass produces dispersion without deviation.The angle off teh flint glass prism is `15^@`.Calculate teh angle of crown glass prism and the angular separation of the red and violet rays on emregence from the spectroscope .(`mu` for crown glass = 1.52,`mu`for flint glass=1.65 , `omega` for crown glass 0.02 , `omega` for flint glass =0.03).
