100
Waves do not carry matter, they carry this.
What is energy?
100
A green apple reflects this color.
What is green?
100
Frequency is measured in this
What are hertz (Hz)?
100
The bending or changing direction of a wave as it passes from one medium to another is called this.
What is refraction?
100
This is what light energy that travels by radiation is called.
What is radiant energy?
200
When looking at a transverse wave, this is what the "peaks" are called.
What are crests?
200
This color absorbs most light out of any color.
What is black?
200
As the frequency of a wave increases, the wavelength will do this.
What is decrease?
200
If a wave speeds up in a different medium, will it refract towards or away from the normal? Draw a picture if you need to.
What is away from the normal?
200
On the electromagnetic spectrum, these have the longest wavelengths.
What are radio waves?
300
The distance from crest to crest is called this.
What is a wavelength?
300
This color has the longest, slowest waves. The wavelength is approximately 700nm
What is red?
300
If a wave oscillates 100 times per second, what is the frequency?
What is 100 Hz?
300
This scientist proved that white light contains colors
Who is Sir Isaac Newton?
300
On the electromagnetic spectrum, these waves have the highest frequency.
What are gamma rays?
400
The height of the wave crest or the wave trough is called this.
What is amplitude?
400
This color has short fast waves, at approximately 400nm
What is blue?
400
If a wave oscillates 1000 times in 10 seconds, what is the frequency?
What is 100 Hz
400
This is what happens to colors that are not reflected when they hit your t-shirt.
What is absorbed?
400
These types of waves are used in satellites.
What are microwaves?
500
The amplitude is related to the amount of this that the wave has.
What is energy?
500
These are the 3 primary colors.
What are red, green, and blue?
500
In this type of wave, matter in a medium moves back and forth in the SAME direction as the wave travels.
What is a compression wave?
500
These are the three secondary colors.
What is cyan, yellow, and magenta?
500
These types of waves have been used in moderation to kill cancer cells.
