Due to the variation in refractive indices for the two types of light, they exit traveling in separate parallel paths.

1. Light exits in parallel paths.
2. Both types of light have identical refractive indices.
3. The refractive indices for the two lights differ.
4. The light does not exit in parallel paths.

Correct answer: Light exits in parallel paths.

Solution

When light passes through a medium with different refractive indices for different wavelengths, the light rays emerge in parallel directions due to refraction. This is consistent with the given statement.
