1
New cards

Amplitude

The maximum displacement of a point on the wave from its undisturbed (rest) position.

2
New cards

Wavelength

The distance between two consecutive points in phase, such as from one crest to the next.

3
New cards

Frequency

The number of complete waves (cycles) passing a fixed point per second, measured in Hertz (Hz).

4
New cards

Period

The time taken to complete one full cycle or oscillation, measured in seconds (s).

5
New cards

Cycle

One complete vibration or oscillation of a wave (one full crest and one full trough).

6
New cards

Wavefront

An imaginary line or surface that connects all adjacent points on a wave that are in the same phase.

7
New cards

Formula for frequency

Frequency = 1/T (Period).

8
New cards

Formula for wave speed

Wavespeed = Frequency x Wavelength.

9
New cards

Formula for period

Period = time/number of waves.

10
New cards

Formula for frequency (alternative)

Frequency = number of waves/time.
