Question

what is the correct definition of refraction?
light passes through an object without being affected by that object.
light bounces back from an object at the same angle and intensity that the object received it.
a change in the direction of light when it goes from one medium into a different medium.
when light strikes an object, it doesnt pass through and it does not change direction.

Explanation:

• The first option describes unimpeded light transmission, not refraction.
• The second option defines reflection, not refraction.
• The third option matches the standard definition of refraction, which is the directional change of light when moving between two distinct media.
• The fourth option describes an opaque object blocking light, not refraction.

Answer:

A change in the direction of light when it goes from one medium into a different medium.
