Wave Basics
Energy transferred through a medium without permanent movement of matter.
What is a wave?
Difference from crest to crest
What is wavelength?
The velocity of a wave with a frequency of 5 Hz and a wavelength of 2m.
What is 10 m/s?
Type of wave sound is
What is longitudinal?
Only part of the EM spectrum humans can see
What is visible light?
Wave bouncing off a surface
What is reflection?
This happens to particles in a medium as a wave passes through.
What is vibrate in place?
Number of waves passing a point per second.
What is frequency?
The frequency of a wave traveling at 12 m/s with a wavelength of 3m.
What is 4 Hz?
Why sound is a mechanical wave.
It requires a medium.
Type of wave with longest wavelength
What are radio waves?
Wave bending when entering a new medium
What is refraction
The tye pf wave that requires a medium.
What is a mechanical wave?
Height of a wave from rest position.
What is amplitude?
The wavelength of a wave with a velocity of 20 m/s and a frequency of 10 Hz.
What is 2m?
Medium where sound travels fastest.
What is a solid?
Type of wave with shortest wavelength
What are gamma rays?
Wave spreading around an obstacle
What is diffraction?
A wave that can travel through empty space.
What is an electromagnetic wave?
Highest point on a wave.
What is crest?
If wavelength increases and speed stays constant, frequency does this.
What is decrease?
What regions of compression and expansion in sound waves are called
What are compressions and rarefactions?
All EM waves travel at this speed in a vacuum
What is the speed of light?
When waves combine and increase amplitude.
What is constructive interference?
This is an example of energy transfer without matter movement.
(answers vary)
Lowest point on a wave.
What is trough?
If frequency increases, wavelength does this.
What is decrease?
Why sound cannot travel through space.
There is no medium
EM waves do NOT require this.
What is a medium?
When waves combine and cancel out.
What is destructive interference?
