Hint

The path of a ray of light passing through a rectangular glass slab is determined by the angle of incidence and the refractive indices of the two media.

Quick oral answer

The trace most likely to be correct is that of student IV. The path of a ray of light passing through a rectangular glass slab is determined by the angle of incidence and the refractive indices of the two media. In this case, the angle of incidence is 90 degrees, so the angle of refraction is also 90 degrees. This means that the ray will pass straight through the glass slab without being bent.

Common mistakes

  1. 1.Assuming that the ray will be bent as it passes through the glass slab.
  2. 2.Not considering the angle of incidence and the refractive indices of the two media.

Analysis and explanation

The path of a ray of light passing through a rectangular glass slab is determined by the angle of incidence and the refractive indices of the two media. In this case, the angle of incidence is 90 degrees, so the angle of refraction is also 90 degrees. This means that the ray will pass straight through the glass slab without being bent.

Interesting facts

The path of a ray of light passing through a rectangular glass slab is determined by the angle of incidence and the refractive indices of the two media.

The angle of refraction is determined by the angle of incidence and the refractive indices of the two media.
