when blue light shines on it, the ball appears blue.
What does this tell you about how the ball reflects light?
Choose 1 answer:
A
It reflects red and green frequencies of light.
It reflects no frequencies of light.
It only reflects blue frequencies of light.

Answer 1

When red or green light shines on the ball, it appears black, but when blue light shines on it, the ball looks blue. This suggests that the ball absorbs red and green light but reflects blue light.

Step-by-step explanation:

When red or green light shines on the ball, it appears black, but when blue light shines on it, the ball looks blue. This observation tells us that the ball absorbs red and green frequencies of light but reflects blue frequencies of light. The colors we perceive are the result of the light that is reflected off an object, so if a ball appears blue, it means that it is reflecting blue light while absorbing other frequencies.
