Wave Properties
Any disturbance that transfers energy from place to place.
What is a wave?
When a wave bounces off and heads in a different direction.
What is reflection?
If you stand at the Grand Canyon and yell you hear an echo, this is an example of what?
What is reflection?
A material that reflects or absorbs all of the light that is strikes.
What is opaque?
How you greet someone.
What is a wave?
A wave that moves through some type of medium.
What is a mechanical wave?
The bending of a wave due to a change in speed.
What is refraction?
A sound which refers to how high or low the sound seems.
What is pitch?
The surface of a mirror that curves inward.
What is concave?
You can hear this wave.
What is a sound wave?
The number of waves that pass a given point in a certain amount of time.
What is frequency?
The phenomenon which occurs when two waves meet while traveling along the same medium.
What is wave interference?
Loudness can be measured with this unit.
What is a decibel?
The color with the longest wavelength.
Red
You can hang ten on this wave.
What is an ocean wave?
The distance a wave travels before repeating.
What is wavelength?
When two waves interfere with one another creating a higher amplitude.
What is constructive interference?
The amount of energy a sound wave carries per second through a unit area.
What is intensity?
Monica was using different colored pieces of clear plastic for an art project. Her little brother came and scattered the plastic all over the photograph of the image she was using as a guide. As she was cleaning up, she noticed that the image appeared differently behind certain colors of plastic. Why was this?
All colors except the one that matches the plastic can pass through, leaving that color black.
I am the fastest wave in the universe.
What is a light wave?
Half of the vertical distance from the trough to the crest of the wave.
What is the amplitude?
In a standing wave, the areas on the wave where the amplitude is zero are called_____, and the areas on the wave where the amplitude is the greatest are known as_______. (pg. 24)
What are nodes and antinodes?
The change in frequency (pitch) of the sound wave in relation to an observer.
What is the Doppler Effect?
If you found yourself on one side of this two-way mirror, what is the best way you could prevent someone on the other side from observing you?
Turn off the light on your side.
Waves that don't have to travel through a medium.
What are electromagnetic waves?
