Direction of light can be changed by_______

1.	Direction of light can be changed by_______
Answer» Answer: Explanation: Refraction. Light waves change speed when they pass across the boundary between two substances with a DIFFERENT DENSITY, such as air and glass. This causes them to change DIRECTION, an effect called refraction. My personal opinion is that light does not move SLOWER through matter, it travels through more space.
