Math and wave type
Sound waves are a common example of this type of wave...
Longitudinal
Sound bends around corners better than light as an example of this wave interaction
Diffraction
In, sound decreasing the amplitude makes the sound.....
quieter (less loud)
As harmonics increase, the frequency of the standing wave....
increases
This section of the visible light spectrum has the longest wavelength
red
This wave moves at a right angle (perpendicular) to the direction of motion of the wave
Transverse wave
This idea is used in noise canceling headphones as an opposite sound wave is sent out to cancel the noise around you
Total destructive interference
Light or electromagnetic waves are this type of wave
transverse
As the number of harmonics increase, the wavelength...
decreases
These two sections of the electromagnetic spectrum are often used in the medical field for looking inside our bodies!
Gamma rays and x-rays
If the wavelength is 4 m and the velocity is 3 m/s, this would be the frequency of the wave (include units!)
0.75 Hz
An echo is an example of this wave interaction
Reflection
This is the property of the wave that appears to change when the doppler effect occurs
the frequency
How many waves are in the third harmonic?
1.5 waves
This is term to describe the light that is high energy and therefore dangerous to your cells!
Ionizing radiation
This is what waves move from one location to another
energy!
Fisherman have to know physics to understand that this wave interference occurs which makes the fish appear to be in a different spot then they are in real life
Refraction
A sonic boom occurs because the aircraft is.....
moving at or faster then the speed of sound
If the first harmonic is at 15 Hz, where would you expect to find the 5th harmonic?
75 Hz
This section of the electromagnetic spectrum is where we get waves used in our cell phones. They are a bigger wave so we sometimes lose cell signal
Microwaves
A sound wave is traveling along at 340 m/s and is 5 m long, what is its period?
0.014 seconds
This wave interference causes standing waves to form
Constructive interference
This is good evidence of the big bang theory as it implies the universe is expanding instead of shrinking or staying the same size
redshift
If the wavelength of the first harmonic is 3 m, what is the wavelength of the 4th harmonic (assuming the system stays the same)?
0.75 m
This section has a slightly higher frequency than the visible spectrum
ultraviolet (UV) rays
