Please adA combination of two prisms, one of flint and other of crown glass produces dispersion without deviation. The angle of flint glass prism is `15^@`. Calculate the angle of crown glass prism and angular separation of red and violet rays on emergence 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`).
