Light Waves Review

Front

What is light energy?

Back

Light energy is a form of energy that travels in waves and can be seen by the human eye. It is responsible for the colors we see and can cause changes in materials, such as color changes in special nail polish.

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave. It is the point where the wave reaches its maximum height.

Front

What do all waves carry?

Back

All waves carry energy.

Front

What is amplitude in a wave?

Back

Amplitude is the height of a wave from its rest position to its crest. It measures the energy of the wave; greater amplitude means more energy.

Front

How does sunlight affect certain materials?

Back

Sunlight can provide energy to materials, causing changes such as color change in special nail polish or drying glue.

Front

What is the difference between sunlight and light from a desk lamp?

Back

Sunlight contains a broader spectrum of light and more energy compared to the light from a desk lamp, which may not provide enough energy for certain reactions.

Front

What is the role of energy in wave behavior?

Back

Energy is what allows waves to cause changes in materials, such as heating, moving, or altering their state.

Front

What happens to light when it hits an object?

Back

When light hits an object, it can be reflected, absorbed, or transmitted, depending on the properties of the object.

Front

What is the definition of reflection in terms of light?

Back

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Front

What is absorption in the context of light?

Back

Absorption is the process by which an object takes in light energy, which can lead to changes in temperature or state.
