In what direction does sound waves move in? Explain your answer. If needed give a visual example.
In all directions. Visual example is a truck driving down the road.
100
What is the difference between sound waves and light waves?
Mechanical waves are sound waves that which have a medium. However light waves dont have a meduim.
100
Explain the Doppler Effect.
The change in frequency in a wave.
100
Where is the crest located?
At the top of the wave.
100
Do all waves carry energy?
Yes.
200
What direction does light waves travel in?
In all directions but only in a line.
200
Compare and contrast how different waves move throughout different mediums.
For a light wave its faster. For a sound wave it is more dense. Same as with any other waves.
200
Give and explain an example the Doppler Effect.
When a car goes by at first it is loud but then the sound fades away.
200
Name three types of waves.
gravitational, electromagnetic, mechanical etc.
200
Does energy change in different types of waves?
Yes.
300
At the ocean waves start out fast. But then the force dies down...Why is this?
As the wave moves it loses energy.
300
What is the difference between reflection and refraction.
Reflection is when waves bounce off of a surface and travels at a new angle. Refraction is change in direction of light due to a change in its speed.
300
Give one example of how we use the Doppler Effect in everyday life.
The Doppler Radar.
300
Why does the wave get smaller?
Energy is decreased as the wave moves.
300
What transfers energy from one wave to another?
Wave motion
400
Give an example of a movement in a wave.
Transverse wave.
400
What is the difference between Interference and Diffraction.
Diffraction is when waves bend around an obstacle, while interference is the meeting of two waves.
400
What scientific category does the Doppler Effect fall into?
Physics.
400
What are the two directions of a wave?
Transverse & longitudinal
400
Does the energy ever die in a wave?
Yes.
500
What is the difference in the movement of a transverse and Longitudinal wave?
Longitudinal waves move the same way as sound waves. Transverse waves move and up and down and the energy move side to side.
500
What is the difference between electromagnetic waves and mechanical waves? Include their frequencys and wavelengths.
Mechanical waves are sound waves and they have a meduim. Their frequencys and wavelenghths are longer. Electromagnetic waves have a shorter frequency and wavelenghth.
500
Who came up with the Doppler Effect?
Christian Doppler
500
What happends in a wave?
The energy of a vibration is moving away from the source in the form of a disturbance within the surrounding medium
500
What is wave energy?
Wave energy is transport of energy by ocean surface waves.
