Wavelength and Frequency
Electromagnetic vs. Mechanical
Wave Interactions
Speed through Various Media
Doppler Effect
100
If the wavelength is high, frequency is
What is low?
100
These waves travel faster through solids.
What is mechanical waves (sound is one example)?
100
The bending of waves as they move from one medium to another.
What is refraction?
100
The state of matter where sound travels fastest.
What is solid?
100
For the Doppler effect to occur, the source of the wave must be
What is moving?
200
The color with the longer wavelength will have ______ energy.
What is less?
200
These waves can travel through a vacuum.
What is electromagnetic waves?
200
The bending of waves around a barrier.
What is diffraction?
200
How the speed of sound in liquid compares to the speed of sound in gas.
What is greater than (sound travels faster through liquids if compared to gases)?
200
If the source of the wave is approaching the observer, the waves will be
What is closer together?
300
A wave with a large amplitude will produce a ______ noise.
What is loud?
300
These waves can be transverse or longitudinal.
What is mechanical waves?
300
When a crest of one wave meets the trough of another wave.
What is destructive interference?
300
The change in speed of a wave moving from solid to liquid.
What is slowing down?
300
If a firetruck is moving away from an observer, the observer will hear sounds with a
What is lower pitch?
400
A high pitch noise comes from a wave with a high ______.
What is frequency?
400
Visible waves, radio waves, and gamma rays make up part of this.
What is the electromagnetic spectrum?
400
In light, a mirror, or in sound, an echo.
What is reflection?
400
The reason sound travels slower in gases.
What is less dense? or What is the particles are more spread out?
400
Sound waves behind a jet would have a
What is lower pitch?
500
Wave A: 200Hz, 30dB Wave B: 200Hz, 45dB The relationship between the pitch and loudness of Waves A and B.
What is Wave B is louder and they have the same pitch?
500
The only "thing" that mechanical waves can not travel through.
What is empty space?
500
The color that diffracts the most when light waves go from air to glass.
What is violet? (Shorter wavelength = more interactions with electrons, which slows the wave down more causing it to bend)
500
The state of matter that light travels fastest through?
What is gas? (empty space is not a state of matter)
500
The direction a star is moving (relative to Earth) if the star appears a red/orange color.
What is farther away?
