Question

lesson 27 - properties of waves
what occurs to light as it enters a new medium? select two
□ it is reflected
□ its speed changes
□ light changes color
□ light bends

Explanation:

When light enters a new medium, its speed changes (due to different optical densities of media). This speed change causes refraction, meaning light bends. Reflection is when light bounces off a medium, not when entering it. Color (related to wavelength/frequency) doesn’t change in a new medium.

Answer:

B. Its speed changes, D. light bends
