Amplify, Light Waves Ch 1 & 2

Front

What must an object do to appear green?

Back

It must reflect green light.

Front

What happens when a material absorbs energy from light?

Back

The energy causes the material to change.

Front

Can light cause rocks to glow?

Back

Yes. Rocks can take in energy from the light, causing them to glow.

Front

True or False: A different amplitude makes a wave brighter or dimmer, louder or softer.

Back

True.

Front

How can different types of light be identified?

Back

By their wavelengths.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests of a wave.

Front

What is amplitude in the context of waves?

Back

Amplitude is the height of the wave from its rest position, related to the energy of the wave.

Front

What is the relationship between frequency and energy in light waves?

Back

Higher frequency light waves carry more energy.

Front

What is reflection in terms of light waves?

Back

Reflection is when light bounces off a surface.

Front

What is absorption in the context of light?

Back

Absorption is when a material takes in light energy.
