100

This is the only electromagnetic wave that can be seen by the human eye.

What is visible light.

100
This electromagnetic wave has the least amount of energy.
radio
100
In this interaction of light waves light bounces off of objects.
What is reflection.
100

The maximum height of a wave (intensity: brightness or loudness)

What is amplitude.

100

When a material absorbs energy from light, the energy causes the material to _________.

What is change.

200

The entire light spectrum is know as the?

What is the Electromagnetic Spectrum or EMS.

200
These electromagnetic wave has the shortest wavelength and highest energy.
gamma waves
200

In this interaction of a light wave light bends, causing rainbows and optical illusions such as the staw with water.

What is refraction.

200

The length of a wave peak to peak?

What is Wavelength.

200

A material ________ energy from some types of light but not others.

What is absorbs

300

Light travels in a __________.

What straight line.

300
This electromagnetic wave gives us sun burn.
ultraviolet rays
300

Light will reflect at the ________ angle it hits a mirror.

What is same.

300

The number of peaks in a wave that pass in a second

What is Frequency.

300
In a strawberry this wavelength is reflected.
What is red.
400

Light can travel through space because it is a form of?

What is radiation.

400
These types of electromagnetic rays are slightly dangerous. These waves produce heat.
What are infrared waves.
400
When light energy gets soaked into an object.
absorption.
400

We rate the energy of these waves with decibels.

What are sound waves.

400

When light is transmitted through or reflected off a material, the energy is not absorbed, so the material ________ change.

What is does not.

500

Light carries this with it?

What is Energy.

500
Ultraviolet rays gives us this one good side effect.
What is Vitamin D.
500
____________ objects reflect light.
opaque
500
Light refracts as it passes through our atmosphere. This wavelength is the first to scatter because it has the most energy.
What is the blue wavelength of light.
500
What happens to the wavelengths of light when we see a blue tranlucent object?
All colors are absorbed and blue is transmitted.
