Waves

Types

100

Waves that can travel through space or a vacuum

electromagnetic

200

The matter a transverse wave travels through

medium

300

The direction the particles of a longitudinal wave move in relation to the direction of the wave

parallel

400

The type of wave produced when particles of a substance are moving both parallel and perpedicular to the wave direction

surface

500

An area of a longitudinal wave where the particles of matter are widely spaced

rarefaction

Properties

100

A measure of how far particles move from rest position

amplitude

200

One wave per second

hertz

300

Symbol for the distance from the start of one compression to the start of the next, successive compression

lamda

400

Property or properties of a wave that determine the amount of energy it is transmitting.

frequency and amplitude

500

If a wave has an amplitude of 1.5 m, there are 2.5 crests that pass a given point each second, and the distance from crest to trough is 1.0 m what speed is the wave traveling?

5 m/s

Direction

100

A line drawn perpendicular to a material that will not transmit the available energy

normal

200

When light bends as it travels through glass, water and air this is called

refraction

300

The angle at which a wave encounters a barrier is the 

angle of incidence

400

If a wave strikes a barrier at an angle of 31.267 degrees, at what angle will the wave reflect from the barrier?

31.267 degrees

500

If the opening a wave travels through is larger than the wavelength of the wave then 

diffraction will decrease

Interaction

100

Interaction among waves

interference

200

When the crest of a wave meets the trough of another wave _ will occur.

destructive interference

300

Wave property that is most affected when waves meet in or out of step

amplitude

400

Type of interference applied to decreasing muffler/exhaust noise in cars

destructive interference

500

Type of interference most likely to result in a tsunami

constructive interference

Vibration

100

Waves that do not appears to travel

standing wave

200

Point on a wave that shows no vibration

node

300

Point on a wave that vibrates with the greatest amplitude

antinode

400

Standing waves result from interference of reflected waves that have the same

amplitude, frequency, and speed

500

Wavelength of a wave that is on a 5.00 ft long string, has 4 nodes and 3 anti-nodes.  

3.33 ft
