SOL 5.6 Light Unit Review

What is Point 2?

• Crest
• Trough
• Wavelength
• Height

Light energy is called:

• thermal energy
• radiant energy
• mechanical energy
• sound energy

Light travels in —

• compression waves
• transverse waves
• longitudinal waves
• mechanical waves

Light can travel through outer space. Sound cannot. Why?

• Light needs matter to travel but sound does not.
• Sound wavelengths are too small.
• Light does not need matter to travel but sound does.
• Sound wavelengths cannot be measured.

Radiant energy is important for plants because it allows them to:

• reproduce
• be pollinated
• make food through photosynthesis
• make pollen

The visible spectrum is —

• frequencies
• only the black
• the light people can see
• wavelengths

Sunlight beaming down and causing pavement to warm up is an example of:

• thermal energy transforming into radiant energy
• sound energy transforming into thermal energy
• radiant energy transforming into thermal energy
• radiant energy transforming into electrical energy

When radiant energy from the sun is ___________ it warms land, water, and air.

• absorbed
• reflected
• deflected
• blocked

Which part of the spectrum has the longest wavelength?

• Orange
• Blue
• Red
• Yellow

Which person is creating a transverse wave?

• A boy plays the piano and sings a song.
• A woman cooks something on the stove.
• A girl turns on her flashlight to look for something.
• A man takes a photo of someone.
