Wave Vocab
A disturbance that transfers energy from place to place
What is a "wave"?
Seeing your image in a mirror
What is "reflection"?
Waves that require a medium to travel?
What are "Mechanical Waves"?
Which travels faster: Sound waves or Light waves
What is "Light waves"?
What is "louder/has more energy"?
A wave has a wavelength of 3 m and a frequency of 4 Hz. What is the waves speed?
What is 12 m/s
A solid, liquid or gas that a wave travels through
What is a "medium"
A pencil looks bent in a cup water
What is "refraction"?
Waves that can travel through empty space
What are "Electromagnetic waves"?
Which wave property determines pitch?
What is "Frequency"?
As frequency increases, wavelength ______
What is "decreases"?
If a wave's frequency increases while speed stays the same, what happens to the wavelength?
What is "Decrease"?
When a wave bounces off a surface, what is it called?
What is "reflection"?
Hearing someone around a corner
Sound waves are this type of wave
What is a "Longitudinal wave"?
Which wave property determines loudness?
What is "amplitude"?
A wave with the highest frequency would appear ______ on a graph
What is "more closely spaced"?
What is 3 Hz?
The bending of a wave as it moves into a new medium.
What is "refraction"?
Light disappearing as you swim deeper underwater
What is "absorption"?
Light waves are this type of wave
What is a "transverse wave"?
What is "a medium"?
Using the EM spectrum graph, which wave has the highest energy?
What are "gamma rays"?
Two waves travel at the same speed
Wave A has a frequency of 5 Hz
Wave B has a frequency of 10 Hz
Which wave has a shorter frequency and why?
What is "wave B, becuase higher frequency means shorter wavelength"?
When two waves overlap and combine to form a new wave.
What is "interference"
What is "interference"?
These waves have compressions and rarefactions instead of crests or troughs
What are "Longitudinal waves"?
Why does blue light have more energy than red light?
What is "blue light has shorter wavelength and higher frequency"?
Why are digital signals more reliable than analog signals
They use binary code and are less affected by noise/interference.
A wave has
Frequency - 8 Hz
Wavelength - 0.5 m
1 Calculate the wave speed.
2. If the frequency is double what would happen to the wavelength?
1. What is "4m/s"
2. What is "would decrease by half"?
