Alberta Grade 8 Science – Light And Optical Systems Practice Test

Which statement describes reflection?

Light can be reflected Light can only be absorbed Light cannot interact with surfaces Light travels through walls

Correct Answer:

Light can be reflected

Explanation:

Reflection is when light hits a surface and bounces off instead of being absorbed or passing through. When light meets a smooth surface, the direction it comes in from (the angle of incidence) is equal to the direction it leaves (the angle of reflection), so the light changes direction in a predictable way. The statement that light can be reflected captures what reflection is. The other ideas don’t describe reflection: light can be absorbed, light does interact with surfaces, and most walls are opaque and don’t let light pass through.
