Flashcards in Waves Deck (12):
1

Crest

The highest point of a transverse wave

2

Trough

The lowest point of a transverse wave.

3

Wavelength

-The distance between two waves, the distance between two crests or troughs(transverse)
-Distance between two compressions or rarefactions. (Longitudinal)

4

Frequency

The number of waves that pass a given point per second, measured in hertz (hz)

5

Amplitude

The vertical distance between the crest and the equilibrium, midpoint of wave (transverse)

distance between particles of the medium where it is compressed by the wave (longitudinal)

6

Energy Transfer

Waves transfer energy from one place to another, in a wave the particles transfer energy to other particles and then return to their resting position. Energy is transferred by oscillations.

7

Transverse wave

A transverse wave is a moving wave that is made up of oscillations happening perpendicular to the direction of energy transfer. It can also mean that it is a wave that causes the medium to vibrate at right angles to the direction in which the wave travels.

8

Oscillation

Oscillation refers to any Periodic Motion moving at a distance about the equilibrium position and repeat itself over and over for a period of time

9

Longitudinal Waves

A wave that oscillates back and forth on an axis that is the same as the axis along which the wave travels, (particles move back and forth)

10

Compressions

Cormpressions occur in longitudinal Waves, they are the sections of the waves where particles are closest together, have high pressure and transfer energy to the adjacent particles which allows the wave to travel

11

Rarefactions

Rarefactions are the section of a longitudinal wave where the particles are furthest apart and are at a low pressure, they occur before and after compressions.

12

Period

The time it takes for one wave to pass a given point
Period=1/frequency(hz)
