Question

which statement best describes the refractions of light as it moves from air to glass? (1 point)
○ although the light bends, its speed remains the same as before.
○ light undergoes diffraction due to the difference in the speed of light in air and glass.
○ although the light changes speed, it continues in the same direction as before
○ light bends due to the difference in the speed of light in air and glass

Explanation:

1. Analyze Option 1: The speed of light changes when moving between media (air to glass), so this is incorrect.
2. Analyze Option 2: Refraction, not diffraction, occurs due to speed difference in media. Diffraction is about bending around obstacles, so this is incorrect.
3. Analyze Option 3: When light refracts, its direction changes (bends) when speed changes at an angle to the surface, so this is incorrect.
4. Analyze Option 4: Refraction is the bending of light as it passes between media with different optical densities (which relates to light speed). Air and glass have different light speeds, causing bending. This matches the definition of refraction.

Answer:

Light bends due to the difference in the speed of light in air and glass
