What are the two main types of waves?
Mechanical and Electromagnetic waves
A wave has a crest to crest distance of 2 meters, a rest position to trough distance of 0.4 meters, and vibrates at 60 Hz. What is the wavelength?
2 meters
What is the period of a wave?
The time it takes to complete one full cycle.
What are the two forms of waves?
Transverse and Longitudinal

What is a wave? (define it)
A wave is a disturbance that travels through a medium or space, transferring energy without transferring matter.
A wave has a crest to crest distance of 2 meters, a rest position to trough distance of 0.4 meters, and vibrates at 60 Hz. What is the amplitude?
0.4 meters
What is the frequency of a wave?
The number of cycles per second. The unit used is Hertz (Hz.)
Provide an example of a longitudinal wave.
Sound waves
How does decreasing a wave's amplitude affect its speed?
Changing the amplitude has no effect on wave speed.
Provide an example of a mechanical wave.
sound, water, slinky, seismic waves
A wave has a crest to crest distance of 2 meters, a rest position to trough distance of 0.4 meters, and vibrates at 60 Hz. What is the frequency?
60 Hz, or 60 cycles per second
What is a transverse wave?
Transverse waves have oscillations perpendicular to the direction of wave propagation.
Provide an example of a transverse wave.
electromagnetic waves
How does increasing the frequency of a wave affect its speed?
Provide an example of an electromagnetic wave.
visible light, radio waves, microwaves, infrared waves, ultraviolet waves, x-rays, gamma rays.
A wave has a frequency of 10 Hz., which is 10 cycles per second. What is the period of the wave?
0.1 seconds
What is a longitudinal wave?
Longitudinal waves have oscillations parallel to the direction of wave propagation.
Imitate one of Ulises' sound effects.
That sucked.
What factors affect the speed of a wave?
The nature of the medium, such as mass density and elasticity.
Does matter travel from one side of a wave to another?
No
A wave has a period of 5 seconds. What is the frequency of the wave?
0.2 Hz.
How do you find the speed of a wave?
Take the distance traveled by the wave divided by the time it takes to travel that distance.
Increasing the amount of energy changes a wave in what manner?
It increases the amplitude of the wave.
How is speed related to wavelength and frequency?
speed = frequency x wavelength
