Question

turn the laser on by clicking the red button. which direction the trans- mitted light bends to? away or towards the normal (note that the vertical dotted line is the normal)?

Answer 1

The direction of light bending depends on the indices of refraction of the media, bending toward the normal when entering a denser medium and away when moving to a less dense medium.

Step-by-step explanation:

The direction in which light bends when passing through different media depends on the indices of refraction of the media involved. When a laser beam, which behaves like a ray of light, moves from a medium with a lower index of refraction to a medium with a higher index of refraction, it bends toward the normal. Conversely, when it moves from a medium with a higher index of refraction to one with a lower index, it bends away from the normal. These behaviors are dictated by Snell's Law and are a fundamental concept in the study of optics.
