100
What is the frequency of this wave?
1/4 Hz
100
This is convection. What internal property explains why hot fluids rise and cold fluids sink?
Density
100
This is an example of ____________
Reflection
100
The number of waves per second
frequency
100
The high point of a transverse wave
crest
200
What is the frequency of the wave shown?
1/8 Hz
200
Which material would engage in energy transfer the most efficiently and why?
Iron because the atoms in the space are very close to each other, promoting conduction.
200
We can see the other side because light is ____________ through the glass.
The straw looks distorted because of ___________.
transmitted, refraction.
200
With sound waves, the ________describes how high or low the frequency of a sound is.
pitch
200
Which direction do transverse waves propogate?
Up and down
300
What is the frequency of the wave?
1/2 Hz
300
Explain why the realistic model would be more effective than the hand-drawn model.
The lid of the realistic model is clear, allowing more heat to transmit into the pot.
300
What's the difference between how light and heat interact with our atmosphere?
Light gets transmitted. Heat gets absorbed.
300
The low point of a transverse wave
Trough
300
An extremely bright light would have a high _________________
Amplitude
400
What's the frequency of the wave?
2.5 Hz
400
After you cook a meal, the stove top still feels hot if you put your hand near it because of _____________.
Radiation
400
True or False.
Electromagnetic waves need a medium to pass.
False.
400
The measure of how high or low a sound wave is.
Pitch/Frequency
400
Describe the relationship between frequency and wavelength.
As frequency increases, wavelength decreases.
500
What's the frequency of the wave?
250 Hz

Explain why we need ice-covered water to prevent global warming by using the words "reflection, temperature, and absorption"
Ice-covered water reflects sunlight back into the atmosphere. Without ice-covered water, most of the sunlight is absorbed by ocean, which increases the temperature of our ocean waters.
500
When modeling wave phenomena, the percentages of each wave should add up to ________.
100%
500
Electromagnetic radiation has higher energy when the ____________ of that wave is shorter.
wavelength
500
A waves energy is largely determined by it's _____________
amplitude.
