Transverse and longitudinal waves
What is are the two different types of waves?
100
Small
When frequency is high, wavelength is
100
t = .005 s f = 1/t f = 1/ .005 s f = 200 Hz
A wave has a period of .005 s. What is its frequency?
100
Reflection, refraction, diffraction, and interference.
What are the four different types of wave behaviors?
100
The angle of incidence
What is the incoming angle on a ray tracing called?
200
One crest and one trough.
What classifies a wave length?
200
Hertz
What is the unit for frequency?
200
f=2.00 Hz v=fλ v=5.00 m/s 5.00 m/s=2.00Hz(λ) 2.50 m= λ
A wave has a velocity of 5.00 m/s and a frequency of 2.00 Hz. Find the wavelength.
200
Ray traces
What is the type of drawing used to help rays and their angles of incidence?
200
Sound waves bounce off of a fixed boundary and reflect back.
How do echoes work?
300
A transverse wave
What is the the type of wave with particles that move perpendicular to the direction of travel?
300
Frequency and pitch are related in that the higher frequency something has the higher pitch it has.
Explain how frequency and pitch are related.

v = 25 m/s v=fλ λ = 10 m 25 m/s = f(10m) 2.5 Hz= f
A wave at sea travels with a velocity of 25 m/s. If it has a wavelength of 10 m, what is its frequency?
300
Waves bending around objects.
Describe diffraction in 5 words or less.
300
A real image forms in front of the mirror while a virtual image appears behind the mirror.
Give the difference between a real and virtual image.

Radio, Microwaves, Infrared, Visible, Ultra Violet, X-Ray, Gamma.
What is the order of waves on the electromagnetic spectrum from smallest to largest?
400
A node is when a standing waves hits the line of equilibrium.
What is a node?
400
f = 55 kHz = 55,000 Hz v = fλ λ = 5.0 m v = 55,000 Hz(5.0 m) v= 275,000 m/s
What is the velocity of a wave with a wavelength of 5 m and a frequency of 55 kHz?
400
Refraction happens when the wave's velocity is changed due to a change in medium while reflection is simply a bouncing back of a ray.
What is the difference between refraction and reflection?
400
Th Doppler effect happens when a sound that is far away from you sounds higher in pitch and then after passing you sounds lower in pitch.
Describe the Doppler effect.
500
Polarization requires particles to moving in a different direction than direction of travel, like in transverse waves, but in longitudinal this isn't possible.
Why can't longitudinal waves be polarized?
500
Energy is directly proportional to the square of the wave amplitude. Bigger amplitude means even more energy being transferred.
How is energy and amplitude related?
500
v = 3.00 m/s v = fλ f = 1/t λ = 1.5 m 3.00 m/s = f(1.5m) 2.0 Hz = 1/t 2.0 Hz = f .5 s = t
A wave has a velocity of 3.00 m/s and a wavelength of 1.5 m. Find its period.
500
Constructive waves are when two or more waves run into each while both on the same side of the medium, ex:auditoriums. Destructive interference is when two or more waves run into each other and are on opposite sides of the medium, ex: noise-canceling headphones.
Describe how both constructive and destructive interference work and give an example of each.

A red shift has increasing wavelengths while blue shifts have decreasing wavelengths
How does a red shift differ from a blue shift?
