8th - Light Wave Interactions

Front

What is reflection in the context of light waves?

Back

Reflection is the bouncing of a wave off a surface.

Front

What happens to light when it reflects off a surface?

Back

Light changes direction but stays in the same medium.

Front

What is refraction?

Back

Refraction is the change in direction of a wave as it changes speed when moving from one medium to another.

Front

What causes a pencil to appear broken when placed in water?

Back

The light bends when it passes through water, causing the pencil to appear broken.

Front

What is absorption in wave interactions?

Back

Absorption is the transfer of energy from a wave to the medium through which it travels.

Front

What is transmission in the context of light waves?

Back

Transmission is the passing of light through a medium without being absorbed.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings.

Front

How does the speed of light change in different mediums?

Back

Light travels at different speeds in different mediums, which can cause refraction.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What is the difference between reflection and refraction?

Back

Reflection involves bouncing off a surface, while refraction involves bending as light passes into a different medium.
