Properties
Any disturbance that transfers energy from point A to point B.
What is a wave
when a wave bounces off of an obstruction
What is reflection
The type of wave sound uses to travel, and one that contains compressions and rarefactions.
What is a longitudinal wave
The type of wave that does not require a medium to travel through
What is an electromagnetic wave
Materials that allow the most light through them
What is transparent
Waves that require a medium to travel.
What is a mechanical wave
When a wave changes speed as it moves one one medium to another medium.
What is refraction
The process of sound waves striking a surface and losing energy to that surface
What is absorption
The electromagnetic wave with the longest wavelength
What are radiowaves
Materials that do not allow light through them
What is opaque
the distance a wave travels before it repeats itself
What is a wavelength
When waves are able to bend around objects
What is diffraction
The ability of sound waves to bend around the edges of a doorway
What is diffraction
The electromagnetic wave that allows us to view color
What is visible light
The type of reflection that shows a mirror image
What is regular reflection
The number of times a wave repeats in a given amount of time; measured in hertz.
When two waves of a similar size collide and form a wave with an amplitude greater than either of the original waves
What is constructive interference
The type of wave sound uses which requires matter to travel. Hint: not longitudinal
The effect that occurs when a beam of high-frequency light hits a metal, resulting in the loss of electrons from the metal
What is the photoelectric effect
The type of reflection that occurs when parallel rays of light hit an uneven surface
What is diffuse reflection
The equation to find the speed of a wave
What is wavelength times frequency
When a wave appears to stand still in one place due to destructive interference between two colliding waves, producing a point of zero amplitude
What is a standing wave
The state of matter that allows sound to travel fastest
What is solid
What are electric and magnetic fields
The three types of mirrors we discussed
What are plane, convex, and concave
