Wave Properties
The distance between the crest/trough and the midline of a mechanical wave
Amplitude
What is it called when a wave bounces off a substance and heads in another direction.
Reflection
When a sound wave is absorbed by an object what occurs to its energy?
Loses energy.
What type of EM wave has the lowest frequency?
Radio Waves
Sound wave frequency of an A minor is 51.91 Hz and the wavelength is .82m. What is the speed of this wave?

Why do music studios have dark and clothed walls?
As we move on the spectrum of visible light, wavelength does what?
Increases
What happens to the image when light encounters a convex mirror?
The object is smaller than it actually is.
The two types of mechanical waves.
Longitudinal and Transverse waves.
Refraction occurs due to a change of ( ) which results in a change of ( )
medium and speed
You are walking around a corner and you hear Mr Krupa talking about your grades. Why can you hear him before you see him?
Diffraction.
As we move toward a higher frequency, the energy of an EM wave goes
Up.
What is the difference between a real and virtual image?
Real images are upside down, Virtual are always right side up
How are frequency and wavelength related?
They vary inversely. Ex One doubles the other halves.
When a wave is interfered, such that the wave appears to be not in motion it is called this.
Standing wave.
