A convexo-concave diverging lens is made of glass of refractive index 1.5 and focal length 24 cm. Radius of curvature for one surface is double that of the other. Then radii of curvature for the two surfaces are (in cm)

A ray of light passes from vacuum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction then the angle of incidence is
