Choices: - radiation energy - caffeine - calories - chemical energy A:
A: chemical energy
Question: Answer the following question given this paragraph: The angle at which light bends when it enters a different medium depends on its change in speed. The greater the change in speed, the greater the angle of refraction is. For example, light refracts more when it passes from air to diamond than it does when it passes from air to water. That's because the speed of light is slower in diamond than it is in water. Q: The angle at which light bends when it enters a different medium is known as what? Choices: - bounce - frequency - resonance - refraction A:
Answer: refraction
