Solution
The correct option is C a reflected ray and a refracted ray and the angle between them would be less than 1800−2θ There will be partial reflection and partial refraction of the incident ray of light. Now since the ray of light gets refracted at an angle greater than the incident angle, the angular difference between the refracted ray and the incident ray will be less than 180−2θ
