This is caused by lengthened soundwaves as the source of the waves moves away from the Observer.
What is the Doppler Effect?
This is the overlap of two waves that are in-phase, leading to a maxima.
What is constructive interference?
These types of waves don't travel, but are instead trapped between two points.
What is a Standing Wave?
The overlapping of two waves with a path difference that is not a whole number, leading to minima.
What is destructive interference?
This is the distance between two consecutive, identical points on a wave.
What is Wavelength?
This pulsing loudness is heard when two slightly different frequencies are heard at the same time.
What is Beats?
When you shine light through this, you get a pattern of bright and dark spots.
What is a Diffraction Grating?
This is the point in a standing wave with no movement, despite the wave travelling through it.
What is a Node?
The property of all waves that leads to them spreading out from a central point
What is Diffraction?
This property of sound waves determines how loudly we hear it.
What is Amplitude?
According to v = fλ, the shortening of this is what causes the increased frequency during the Doppler effect
What is wavelength?
The different wavelengths of light showing a pattern at each maxima from the central maxima
What is Rainbow spectrum?
Doing this increases the velocity of a wave in a string
What is tightening?
You can calculate this by subtracting one frequency from the other, similar frequency.
What is the Beat Frequency?
This colour of light in the visible spectrum has the longest wavelength
What is Red Light?
A source moving like this results in a changing perceived frequency
What is Accelerating?
This occurs when all wavelengths of light meet with zero path difference.
This occurs when all wavelengths of light meet with zero path difference.
This type of standing wave has Antinodes at both ends.
What is an open-pipe?
This temperature of air leads to a faster transmission of sound waves through it.
What is warm air?
This measurement is the number of complete waves that pass a fixed point each second.
What is Frequency?
On a graph, this increases the closer the observer is to the moving source of the sound.
What is slope angle?
This is the reason that nλ = dx/L is not always appropriate to calculate the distance between maxima.
What is Small Angle Approximation?
Causing objects to respond to nearby noises, this is the frequency where the wavelength fits perfectly inside the object, allowing it to vibrate in response to sound.
What is Resonant Frequency?
This is the point in a standing wave with maximum displacement, the greatest movement of the particles.
What is an Antinode?
This property of light waves determines the colour we perceive.
What is Wavelength?
