Question

In which scenario would you expect the highest amount of refraction to occur when an electromagnetic wave passes from one medium to another?

• A. When the incident angle is close to 0 degrees.
• B. When the incident angle is close to 90 degrees.
• C. When the incident angle is close to 45 degrees.
• D. Refraction is independent of the incident angle.

Hint:

Refraction is most pronounced when the incident angle is large, especially as it approaches 90 degrees.

Answer 1

The Correct Option is B

Refraction is greatest when the incident angle is close to 90 degrees because the wave bends more sharply as it approaches the boundary between two media. The larger the angle of incidence, the greater the change in the direction of propagation.
