100

This type of wave can travel through a medium or a vacuum. 

EM

100

These waves require a medium to travel.

Mechanical

100

Sound travels fastest in a _______ (solid, liquid, gas) because of the _________ (INCREASED or DECREASED) distance between the particles.

SOLID and DECREASED

100

What do we call the HEIGHT of a wave? 

Amplitude 

100

Light is this kind of wave.

Electromagnetic 

200

The amount of wavelengths passing through an object in a given amount of time

Frequency

200

True or false: mechanical waves can travel through more than one medium. 

True

200

What causes sound to travel? 

Vibration 

200

What does high frequency mean for a waves energy and wavelength? 

Short wavelength 

High energy 

200

A flow or transfer of energy in the form of oscillation through a medium – space or mass is called ____.

A wave

300

All EM waves travel this way.

Transverse (perpendicular)

300

Give 4 examples of mechanical waves.

Spring, rope, water, earthquake

300
Why can't sound travel in space or a vacuum?
Sound must have atoms (especially gas atoms) in order to travel, and there are no atoms in a vacuum or space.
300

What is the property of a wave with a low frequency? 

Longer wavelengths waves

Lower energy waves

300

Both em and mechanical waves cannot transmit _______. 

Matter

400

Give 4 examples of an electromagnetic wave.

Radio, Infrared, Visible Light, UV, X-Ray, Gamma, Micro

400

List 2 characteristics of a transverse wave.

400

___________ depends on the density of the medium the wave is traveling through. 

Wave Speed

400

HOW do EM waves travel?

Through electric and magnetic fields. 

500

An Electromagnetic wave (light) travels fastest in a _______. Because _____________.

Gas or a vacuum where there are no atoms to slow it down.

500

What type of movement can mechanical waves have?

Transverse and Longitudinal 

(perpendicular or parallel) 

500

How does sonar detect an object in water?

A- by sending sound waves that reflect off the object

B- by sending sound waves that are absorbed

C- by sending sound waves to detect the composition

A- by sending sound waves that reflect off the object
