A wave is incident on a bounix -;mgld1,easo/ukk( v j/a ,dary betwex k rdcstsm309n0:/sz en two media, $X$ and $Y$. The wave travels faster in medium $Y$ than in medium $X$
Which of the following diagrams shows a possible path for this wave?



A.
B.
C.
D.


参考答案:  D


本题详细解析:
Explanation:
The wave is faster in medium $Y$ than in medium $X$. As a result, the ray representing the wave is expected to bend away from the normal, refracting into the original medium.
If the angle of incidence exceeds the critical angle, however, the angle of refraction will be undefined and the wave will undergo total internal reflection.
This is exactly what is shown by Option D, which is the correct response.
Option A shows the ray bending towards the normal, Option C shows no bending at all, and Option B shows an impossible path for the wave to travel.
