Transverse Waves
These are needed for transverse waves to occur
What are vibrations?
These type of waves are an example of longitudinal waves
What are sound waves?
This distance between two crests
What is the wavelength
The trough
What is the bottom most part of a wave?
3 wave crests go by in 6 seconds. If the distance between wave crests is 1 m, what is the wavelength of the waves?
What is 0.5m
A type of wave considered a transverse wave
What is a light or electromagnetic wave?
In longitudinal waves, particles move _______ with the movement of energy.
What is parallel?
Determines how fast a wave travels
What is the medium?
This is a measure of the number of complete waves that pass by a point per second.
What is frequency?
An ambulance is moving towards you at 50mph, as the ambulances moves past you, the pitch of the siren drops. This is due to a change in the observed _______
What is frequency
In transverse waves, particles move ____________ to the energy movement of the wave.
What is perpendicular?
Longitudinal Waves travel faster in ______ mediums
What is a solid?
In a standing wave pattern, how many wavelengths are in the first harmonic?
What is one-half
This part of a wave is related to the intensity of a given wave
What is amplitude?
What is the Doppler effect?
What is the change in observed frequency due to a moving wave source.
A transverse waves carry ________ from one point to another.
What is Energy?
This can effect how fast sound waves travel in air.
What is the temperature?
A the fifth harmonic is seen on a standing wave.
How many nodes and anti-nodes are there?
What is 5 Antinodes, 6 Nodes
This allows energy to move from one place to another while the particles remain stationary
What is a wave?
A hiker is in a Canyon and yells at his friend who is to far ahead. He hears his echo 0.5 seconds later. If the speed of sound in air is 345m/s, how far away is the Canyon wall?
What what is 86 m.
Transverse waves travel fastest through what type of medium?
What is a less dense medium (vacuum)?
Sound waves travel faster in a solid than in a liquid because of this.
What is the small spacing between molecules allowing collisions to happen more frequently?
What is 2m
This is the opposite of frequency or how long it takes one wave to go by.
What is the Period
A destroyer is using sonar to find a submarine in the ocean. The sonar ping returns to the ship 4 seconds later. How deep is the submarine? Speed of sound in sea water is 1500 m/s
What is 3000 m.
