Wave Foundations
The type of wave motion where the disturbance is parallel to the direction of travel.
A longitudinal wave.
The distance between two consecutive crests or troughs.
Its wavelength.
A wave will travel faster or slower in a solid compared to a gas
faster
Are microwaves damaging to human health?
NO!
verbalize what this equation stands for: v=fλ
"Velocity equals frequency times wavelength"
The maximum displacement (height) from the equilibrium position.
The Amplitude.
The measure of the number of waves that travel through a point each second.
Frequency
Infrared sits below visible light on the EM spectrum, explain its energy, frequency, and wavelength in comparison.
Infrared has lower energy, lower frequency, and longer wavelength than visible light.
This type of wave can travel through a vacuum.
An electromagnetic wave
The wave speed of a wave with wavelength 4 m and frequency 2 Hz.
8 m/s
Waves that require a medium to travel through.
A Mechanical wave
The speed at which a wave disturbance moves through a medium.
What is Wave velocity (or speed of propagation)
When light moves from air into a liquid (water), what happens to wave velocity?
What is It goes down (opposite of sound waves)
radiant energy that consists of oscillating electric and magnetic fields (trick question: more vocabulary)
Electromagnetic radiation
what does c represent in the equation: frequency equals c divided by lambda?
What is speed of light
The type of wave motion where the disturbance is perpendicular to the direction of travel.
The change in the observed pitch of a sound, due to relative motion between the source and the observer. A
What is the Doppler Effect
If two EM waves travel through a vacuum and one has twice the frequency of the other, this must be true of their wavelengths.
fields produced by a moving charged particle.
What is electric and magnetic fields
The wavelength of a sound wave traveling at 340 m/s with a frequency of 170 Hz.
What is 2.0 m
The time required for one complete wave cycle.
Its period.
The process that changes the electrical balance within an atom. (think higher energy waves)
What is Ionization
If wavelength stays constant and frequency doubles, this happens to wave speed.
It also doubles.
Compare the frequencies and wavelengths of X-rays to visible light.
X-rays have higher frequencies and shorter wavelengths.
The period of a wave with a frequency of 5 Hz.
What is 0.20 s.
