Cách sử dụng
Refraction is when light waves change direction as they pass through a different material, like when light from the sun moves through water or a magnifying glass. Refraction is important because it helps us see things clearly and can create cool visual effects in nature. You might hear the word refraction in science class or when talking about how a lens works.
