Define the wave
100
An Electromagnetic wave travels fastest in a _______.
Gas or a vacuum where there are no atoms to slow it down.
100
Sound travels fastest in a _______ because of the INCREASED or DECREASED distance between the particles.
SOLID and DECREASED
100

Sound waves and light waves are similar to earthquake (seismic) waves because they all...

transmit or carry energy

100

Type of wave that does not need a medium

Electromagnetic

100
Measured from rest position to crest or trough. 

Amplitude

200
All colors of light mixed together create ___________.
White
200
Sound travels slowest in a __________ because of the INCREASED or DECREASED distance between the particles.
GAS and INCREASED
200

What would happen to the wavelength if the frequency was doubled?


the wavelength would be halved

200

Type of wave that requires a medium

Mechanical

200

Radiant energy is carried on this wave

Electromagnetic

300
What color of light has the longest wavelength (least amount of energy)?
Red
300

If we doubles amplitude on a sound wave..... What would the difference in the sound register as in our ears?

Twice as loud

300

Particles in water in an ocean wave move

in a circle (Oscillation)

300

Type of wave that oscillates perpendicular to the source

Transverse

300

Sounds is a ________ wave.... (give one)

Longitudinal, Mechanical

400
What is the most dangerous part of the EM spectrum that can harm us?
Gamma Rays
400

Why can't sound travel in space or a vacuum?

Sound must have atoms in order to travel, and there are no atoms in a vacuum or space.

400

What happens to the frequency of a wave when the amplitude is tripled?

amplitude does not affect frequency

400

The time it takes for one wave cycle to travel through a given point.

Period

400

P waves are ______ (Provide 1)

Longitudinal, Mechanical

500

Name ONE use for 4 types of EMS waves.

Various

500

If frequency was increased in sound waves... what would the sound difference be perceived as in our ears?

Much higher pitch

500

Moves energy parallel to the source

Longtitudinal

500

Type of wave that oscillates parallel to the direction of motion.

Longitudinal

500

Why does an S wave arrive second? What type of wave is it?

Transverse waves, they arrive second because they can only travel through solids.
