Wave calculations
Describe the two variables needed to calculate wave speed.
What is wavelength and frequency?
A disturbance or movement that transfers energy. State the correct term.
What is a wave?
The unit we use to measure frequency
What is Hertz?
The distance from the midpoint of a wave to the top of the transverse wave. (Or the distance from the midpoint to the bottom of the transverse wave)
What is amplitude?
A category of waves that can travel through a medium or a vacuum
What is an electromagnetic wave?
A wave has a speed of 200 m/s and a frequency of 84 Hz. Calculate the wavelength.
What is 2.4 m?
Sound waves travel fastest through this state of matter.
What are solids?
State the reason why sound waves cannot travel in space?
What is no medium is present?
The lowest point of a transverse wave.
What is the trough?
Transverse waves move ____________ to the direction of energy transferred.
What is perpendicular?
If the wavelength is 4 m and the velocity is 3 m/s, then the frequency of the wave is?
What is 0.75 Hz?
The visible color that has the longest wavelength.
What is red?
Low pressure areas of a longitudinal wave where particles of the wave are spread out
What is a rarefaction?
The measurement of a wave from crest to crest (or trough to trough)
What is wavelength?
Electromagnetic waves are an example of this type of wave.
What is a transverse wave?
If the wavelength is 5 m and the frequency is 5 Hz, what is the wave velocity?
What is 25 m/s?
Black lights, tanning beds, and the sun all produce this type of electromagnetic RAY
What are ultraviolet rays?
Every wave, regardless of type or medium, transfers this
What is energy?
The number of waves that pass a given point per second.
What is frequency?
The spreading of waves around obstacles and through openings.
What is diffraction?
The lowest frequency we can hear is about 20 Hz. Calculate the wavelength associated with this frequency for sound that travels at 340 m/s. How long is the wavelength?
What is 17 meters?
If the amplitude is high, the energy is...
What is high?
The unit Hertz is equal to..........
What is cycles per second?
Frequency and energy have this type of relationship.
What is direct or proportional?
This type of wave requires a medium and the energy moves in the same direction (parallel) to the medium
What is a longitudinal wave?
