On a crisp spring morning, Sue could see a mirror image of the colorful trees in the water of the lake. What causes this mirror image?
Penquin houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave ____________.
The speed of sound varies depending on many factors including temperature, pressure, and humidity, but it is typically found to be approximately 550 m/s. What is the frequency of a sound wave with a wavelength of 0.2 m?
Many new headphones on the market are called "noise reducing" because they take sound waves that come in from the outside and add a sound wave to it that is exactly opposite (out of phase) to it; these add together to make no noise. This is a good example of sound wave ______________________.

Lable the: Crest, trough, Amplitude, wavelengh
In a ____________________ wave the matter in the medium moves back and forth at right angles to the direction that the wave travels.
The ___________ of a wave is how many wavelengths pass a fixed point each second.
In a transverse wave, the higher the amplitude, the ___________ energy it carries.
What type of wave is a sound wave?
Lable the compression and rarefaction
Reflection occurs when a wave strikes an object and __________ off of it.
The angle of incidence of a wave is always equal to the angle of _____________.
______________ is the bending of a wave as it moves from one medium to another.
_______________ when two or more waves overlap and combine to form a new wave.
As wavelength increase, the frequency of the wave _______________.
