This is the only electromagnetic wave that can be seen.
What is visible light.
100
This electromagnetic wave has the least amount of energy and disturbs matter
radio
100
In this interaction of light waves, light bounces off of objects.
What is reflection.
100
It's hard to tell exactly where a fish is in water because of ____________.
refraction

What is opaque?
200
These electromagnetic wave has the shortest wavelength and highest frequency and most energy.
gamma waves
200
In this interaction of a light wave light bends, causing rainbows and optical illusions such as the ruler with water.
What is refraction.

400
When light energy gets soaked into an object and transfers color
absorption.
400
Draw compressions and rarefactions on a longitudinal wave
400
The doppler effect causes the __________ of a sound to be ___________.

500
How do eyeglasses use convex or concave lenses to correct vision
What is refracting light to the retina (eye)
500
Ultraviolet rays gives us this one good side effect.
What is Vitamin D.
500
____________ objects reflect light, and the light cannot be seen through them.
opaque
500
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). We see a ring of light around it, which is an example of this.
diffraction
