Does not change the speed or frequency of a wave, but the wave can be flipped upside down.
What is reflection?
100
Electromagnetic waves differ from mechanical waves in that they can travel through this.
What is a vacuum?
100
The electromagnetic spectrum ranks electromagnetic waves based upon these two properties.
What are wavelength and frequency?
200
From crest to crest OR trough to trough on a transverse wave.
What is wavelength?
200
The general equation for calculating wave speed.
What is speed = wavelength x frequency?
200
When a wave enters a medium at an angle, this occurs because one side of the wave moves more slowly than the other.
What is refraction?
200
Electromagnetic waves are transverse waves consisting of changing of electric fields and changing of this kind of field.
What is magnetic fields?
200
These waves have the longest wavelengths and lowest frequencies. They are commonly used in radar, cell phone, and television technology.
What are radio waves?
300
Wavelength of a longitudinal wave.
What is from compression to compression OR rarefaction to rarefaction?
300
One end of a rope is vibrated to produce a wave with a wavelength of 0.25 meters. The frequency of the wave is 3.0 hertz. What is the speed of the wave?
What is 0.75 m/s?
300
A wave does this if its wavelength is large compared to the size of an opening or obstacle it must pass through or around.
What is diffraction?
300
The speed of light through a vacuum.
What is 3 x 10^8 m/s?
300
These waves have the highest frequencies and shortest wavelengths. They are commonly used in cancer treatment, but can be deadly in high concentrations.
What are gamma rays?
400
Travels at a 90 degree angle in comparison to the direction of the wave.
What is a transverse wave?
400
A motorboat is tied to a dock with its motor running. The spinning propeller makes a surface wave in the water with a frequency of 4 Hz and a wavelength of 0.1 meter. What is the speed of the wave?
What is 0.4 m/s?
400
Occurs when two or more waves combine to produce a wave with a larger displacement.
What is constructive interference?
400
While speed of an electromagnetic wave is always the same, these two properties of waves can change.
What is wavelength and frequency?
400
Makes up a small portion of our electromagnetic spectrum and is the only electromagnetic wave type that we can see.
What is visible light?
500
The three types of mechanical waves.
What are longitudinal wave, transverse waves, and surface waves?
500
What is the wavelength of an earthquake wave if it has a speed of 5 km/s and a frequency of 10 Hz?
What is 500 meters?
500
Occurs when two or more waves combine to produce a wave with a smaller displacement.
What is destructive interference?
500
Using the distance between two mountain tops and two 8 sided mirrors rotating at a constant speed, this scientist calculated the speed of light.
Who is Albert Michelson?
500
List the 6 types of electromagnetic waves. Extra points will be earned if you can list them from long wavelength to short wavelength.
What is radio waves (microwaves), infrared waves, visible light, ultraviolet rays, x-rays, gamma rays.
