Refraction
Understand the Problem
The question is likely asking for information about the concept of refraction in physics, which involves how light changes direction when entering a different medium.
Answer
Refraction is the change in direction of a wave due to a change in speed when it passes between different mediums.
Refraction is the change in direction of a wave passing from one medium to another caused by its change in speed.
Answer for screen readers
Refraction is the change in direction of a wave passing from one medium to another caused by its change in speed.
More Information
Refraction explains why objects may appear bent or distorted under water and is a key principle behind lenses used in glasses and cameras.
Tips
A common mistake is confusing refraction with reflection, which is the bouncing back of waves, not bending.
