Light energy travels in waves, originates directly from the Sun, and is used by plan
to make food. Scientist use light energy to create lasers for cutting, heating,
measuring. Light energy is so important that it is responsible for the existence
most life forms. Furthermore, light energy is the only visible form of energy. It ca
travel through air, space, water, and glass. Light travels in a straight line until
strikes an object or travels from one medium to another. As it travels from or
medium to another it appears to bend.
Which term is best used to describe the bending of light waves?
A
refraction
B
reflection
C
rotation
D
revolution
La
