relationships between wave lwngth and time period
Answers
Answer:
The main difference between wavelength and period is that the wavelength is the shortest distance between two successive points on a wave that are in phase while period is the time taken for a complete oscillation to take place at a given point.
In one period of a wave, one full cycle (peak through valley
and back to peak) passes by.
That means that the wave has moved by one wavelength.
Since speed is distance traveled / time spent, and a wave
moves a distance of one wavelength in a time of one
period, its speed must be:
speed = distance / time = wavelength / period
v = λ / p
We more often use frequency = 1 / period. Then:
speed = wavelength x frequency
v = λ x f
