Waves

Wave Properties

100

Any disturbance that transfers energy from place to place.

Wave

200

This type of energy that travels as waves does not need a medium to travel.

Electromagnetic radiation

300

An ocean wave in the middle of the ocean is this type of wave.

Mechanical Wave

400

The matter a wave travels through is called a _____.

Medium

500

A mechanical wave cannot travel through a _____.

Vacuum

Wave Measurements

100

What is the peak of a wave called?

Crest

200

A mechanical wave begins when a source of ______ causes a medium to vibrate.

Energy

300

Travels perpendicular (at right angles) to the direction of the source's motion. (Up and down motion)

Transverse Wave

400

How is a wavelength measured?

Distance from crest to crest or trough to trough.

500

This measure is from a wave's resting position to it's highest crest.

Amplitude

Measuring Waves

100

Meters per second is the measurement of a wave's _______.

Speed

200

Mechanical wave that travels in the same direction as the vibrations that produce it is a ______________.

(Used a spring for this.)

Longitudinal Wave

300

The number of times a wave repeats in a given amount of time is _____________.

Frequency

400

Frequency is measured in ______.

Hertz

500

What measurement do we measure wavelength in in science?

Meters or centimeters.

Other Wave Stuff

100

Sound waves move fastest through what state of matter?

Solid

200

Area of a longitudinal wave that is showing the wave energy at work.  For example the expanded part of the spring when energy is being transferred through it is called _____. 

Rarefaction

300

If the amplitude of a wave increases by 3 times, the energy would be how much greater?

9 times greater

400

In a longitudinal wave such as a spring, how to you measure a wavelength?

End of compression to the beginning of compression, or length of the rarefaction.

500

Solve:  ___m/s= 50m x 10 Hz

500 m/s

Wave Behavior

100

Some waves are completely blocked by an obstruction, but their energy is not absorbed or converted to another form of energy.  These types of waves bounce off those obstructions and heads in a different directions.

Reflection

200

You are able to hear around the corner of a building.  This is because of _____.

Diffraction

300

Energy of the wave is transferred to the material it encounters.

Absorption

400

When light waves are transmitted from one medium into another it bends in different directions.

Refraction

500

Type of wave interference where 2 waves add the energy together when they meet and then continue the original energies once they seperate.

Constructive Interference
