B) the wave travels faster in the medium to the left of the interface than in the medium to the right of the interface.
C) the wave is traveling with the same speed on both sides of the interface.
D) the angle of incidence is equal to the angle of refraction.
E) total internal reflection is not possible for a wave traveling from left to right.

Quizplus · Accepted Answer

The figure shows that the wave is bent at the interface, implying a change in the speed of the wave. As the wave is bent towards the normal, it indicates that the wave is slowing down in the medium to the left of the interface compared to the medium to the right. Hence, option A is correct. Option B is incorrect because the figure shows that the wave travels slower in the medium to the left. Option C is also incorrect because there is a change in the speed of the wave at the interface. Option D is not known as the angle of incidence and reflection is not given. Option E is incorrect since the possibility of total internal reflection is not determined from the given information.
