What is a periodic disturbance that transfers energy?
a wave
100
What is the highest point of a wave?
crest
100

What type of wave are sound waves? 

longitudinal

100
What type of waves are light waves?
electromagnetic
100
What is the bouncing back of a light wave after it hits a surface?
reflection
200

What is the matter that waves travel through?

medium

200
What is the lowest point of a wave?
trough
200
If a sound wave is travelling through air and it changes mediums to water, what happens to the speed of the wave?

The wave speed increases.

200

Energy from the sun being trapped in your black tshirt and making you feel warmer is an example of ______.

absorption

200

What is the bending of a wave after it passes through from one medium into another, resulting in a change in speed?

refraction

300
What are waves the require a medium (such as sound)?
mechanical waves
300
What is the distance from a point on one wave to the same point on the next wave?
wavelength
300

What determines how loud or soft a sound is? Hint: think about energy. 

amplitude

300

Give me two examples of electromagnetic waves.

Some examples: microwaves, radio waves, gamma rays, ultraviolet waves, infrared waves.

300

White light hits a red flower. What happens next?

All other colors except red get absorbed. The red wavelength gets reflected and that's why we see the flower as red. 
400
What are waves where the particles move perpendicular to the direction of motion?
transverse waves
400
What is the distance (how high or how low) particles move from the baseline of the wave?
amplitude
400

An increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency. Hint: The tuning forks scenario that we saw in class is an example of this.

Resonance

400

What type of wave is an electromagnetic wave? Hint: how does an electromagnetic wave move?

Transverse wave
400

The angle of incidence equals the angle of ______.

Reflection.

500
What is the medium for seismic waves?
earth/dirt
500

The place on a longitudinal wave where the particles are closer together is called ________.

The place on a longitudinal where the particles are farther apart is called ________.

compression, rarefaction

500

What causes sound waves?

vibrations

500

If a light wave is travelling through air, changes mediums and starts going through water, what happens to the speed of the wave?

It slows down.

500

Two wave crests approach eachother. The waves combine, making the new crest's amplitude the sum of the amplitudes of the original crests. The waves continue as if they had not met. This scenario is an example of ________   ________.

Constructive Interference.
