Flashcards in Wave Behaviour Deck (14):
1

What are waves?

An oscillation that transfers energy

2

What is an electromagnetic wave?

A wave that consists of oscillating electric and magnetic fields, don't need a medium to travel through

3

What are mechanical waves?

Waves that require a medium to travel through

4

What is a longitudinal wave?

A wave whose vibrations are in the same direction as the direction of energy transfer of the wave

5

What is a Transverse wave?

A wave whose vibrations are at right angles to the direction of travel of the wave

6

What is the definition, symbol and unit of Amplitude?

Amplitude = distance from middle to top or bottom of wave
Symbol = A
Unit = m or volts

7

What is the definition, symbol and unit of Wavelength?

Wavelength = distance from one point on a wave to the same point on the next wave
Symbol = λ
Unit = m

8

What is the definition, symbol and unit of Frequency?

Frequency = number of waves/oscillations per second
Symbol = F
Unit = Hz

9

What is the definition, symbol and unit for Time Period?

Time Period = time for one wave to pass a given point
Symbol = T
Unit = s

10

What are the two ways to represent a wave?

Time Trace
Snapshot

11

What does a time trace show?

Shows how displacement varies with time at a particular position

12

What does a Snap shot show?

Shows how displacement varies with distance a particular time

13

What can you measure from a time trace?

Period from any point on a wave to the same point on next wave
Amplitude

14

What can you measure from a Snap shot?

Wavelength
Amplitude
