A Fresnel biprism is to be constructed for use on an optical bench with the slit and the observing screen 180.0 cm apart. The biprism is to be 60.0 cm from the slit. Find the angle between the two refracting surfaces of the biprism if the glass has a refractive index n = 1.520, sodium yellow light is to be used, and the fringes are to be 1.0 mm apart
