What happens to waves when they encounter different materials?

Back

Waves can be reflected, absorbed, or transmitted depending on the material's properties.

What should a model of light waves passing through a transparent material include?

Back

The model should show light waves passing through with some reflection and absorption.

Front

Why do metal surfaces reflect waves?

Back

Metal surfaces are smooth and dense, causing waves to bounce back.

Front

What occurs when a wave encounters a barrier?

Back

The wave will be partially reflected, absorbed, and transmitted depending on the material of the barrier.

What is the best way to demonstrate that fields exist between objects exerting forces?

Back

Use a ruler to measure the distance at which a magnet affects a paperclip.

Front

Define reflection in the context of wave behavior.

Back

Reflection is the bouncing back of a wave when it hits a surface that it cannot pass through.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, converting it to other forms of energy.

Front

What does transmission mean in wave behavior?

Back

Transmission is the passing of a wave through a material without being absorbed or reflected.

Front

What factors affect how waves interact with materials?

Back

The properties of the material, such as density, smoothness, and transparency, affect wave interaction.
