stays the same
either increase or decrease
If the frequency of the wave decreases, the number of waves per second ______?
increases

A sound wave that has higher pitch means that it has higher frequency. This means that when you hear the sound ________
more waves hit your ear
less waves hit your ears
bigger waves hit your ears
longer waves hit your ears
All waves carry energy from one place to another, but some waves carry more energy than others. A leaf falling on water produces waves so small they are hard to see. An earthquake under the ocean can produce huge waves that cause great destruction.
What affects the energy of a wave? Select the all that applies.
The energy in a wave is determined by amplitude, which is the distance from the rest position of a wave to the top or bottom.
The energy in a wave is determined by frequency, which is the number of waves that pass by each second.
arge amplitude waves contain more energy.
The medium (material) moving along with the wave.
A disturbance that transfers energy from place to place through matter or space.
wave
equilibrium position
pulse
vibration
Frequency is the inverse of period.

Select the all that apply.
0.2
1/5
0.5
1/2
1 Hertz is
1 frequency
1 amplitude
1 wavelength
1 cycle per second
How are Electromagnetic waves different from Mechanical waves?
EM waves have very short wavelengths
EM waves can travel through the vacuum of space (without particles)
EM waves transmit energy instead of matter
EM waves can change direction by reflection
The interaction between two waves that meet is called
reflection
refraction
interference
diffraction
What occurs when vibrations traveling through an object match the object’s natural frequency?
reflection
resonance
interference
refraction
If the amplitude of a water wave is 0.2 m and its frequency is 2 Hz, how much distance would a bird sitting on the water’s surface move with every wave? How many times will it do this every second?
The bird will go up and down a distance of 0.4 m. It will do this twice per second.
The bird will go up and down a distance of 0.2 m. It will do this twice per second.
The bird will go up and down a distance of 0.4 m. It will do this once per second.
The bird will go up and down a distance of 0.2 m. It will do this once per second.

destructive interference
constructive interference
reflection
refraction
