C)partial reflection,partial transmission
D)partial reflection,total transmission

Question

Quizplus · Accepted Answer

When a light ray passes from one medium to another, a portion of it reflects back into the first medium and a portion of it is transmitted into the second medium. This is known as partial reflection and partial transmission. In the case of an air-to-glass boundary, the amount of reflection and transmission depends on the angle of incidence and the refractive indices of the two media. Total reflection occurs only when the angle of incidence exceeds the critical angle, which is determined by the refractive indices of the two media. Total transmission occurs when there is no reflection, which is not the case for an air-to-glass boundary. Therefore, option C is the most appropriate choice.
