Question

lesson 27 - properties of waves
what produces a rainbow? select two
○ bending of light
○ refraction
○ reflection
○ light bouncing off an object

Explanation:

A rainbow forms when sunlight enters water droplets, bends (refracts) and splits into colors, reflects off the droplet's inner surface, then refracts again when exiting. Refraction (bending of light through a medium) and reflection (light bouncing inside the droplet) are key processes. "Bending of light" is a general term, but refraction is the specific phenomenon here; reflection is also required.

Answer:

B. refraction, C. reflection
