100
Rock formed by the cooling of magma or lava.
What is igneous?
100
This is the distance from any point on the wave to the next point identical point on that wave.
What is wavelength?
100
This property results from a wave hitting a barrier and then moving in the opposite direction.
What is reflection?
100
Sound is this type of wave.
What is a longitudinal wave?
100
This is the area of the medium between the crest and trough.
What is the rest position, or equilibrium?
200
This rock is makes up most of the oceanic crust and is extrusive.
What is basalt?
200
This is the symbol and unit of frequency.
What is lambda, and Hz?
200
When light moves into a prism it slows down and changes direction, which results in the separation of colors.
What is refraction?
200
Frequency and wavelength determine the ______________ of a particular sound.
What is pitch?
200
This is an ocean wave with an extremely long wavelength that is often produced by a seismic disturbance.
What is tsunami?
300
This type of age can be determined by comparing the layers that different fossils are found in.
What is relative age?
300
When a wavelength increases, but the wave speed stays the same.
What will decrease the waves frequency?
300
This is the reason that red light does not bend as much as blue light when going from air to a denser medium.
What is a longer wavelength?
300
Mediums with a higher ___________ transmit sound faster.
What is density? or elasticity?
300
This type of wave can travel through the vacuum of space.
What is electromagnetic, or light?
400
This is the % of radioactive material left after 3 half lives have passed.
What is 12.5%?
400
The initial disturbance that causes a wave is called a ____________, which then travels through a _____________.
What is pulse, and a medium?
400
This type of wave causes the medium to move perpendicular to the wave direction.
What is a transverse wave?
400
This property makes it possible for one tuning fork to make another tuning fork move without touching it.
What is resonance?
400
______________ is the name for sounds that above the range of human hearing.
What is ultrasonic?
500
How old is a petrified tree with 6.25% of its Carbon-14 remaining?
What is about 21,000 years?
500
A wave moving at 10 meters per second with a wavelength of 2 meters has a frequency of ___________.
What is 5 Hz?
500
This property is what allows noise canceling headphones to work.

This is the type of energy that all sound waves ultimately turn into.
What is heat energy?
