Question

From the following figure :
Find :
(i) Wavelength
(ii) Wave velocity
(iii) Frequency

Answer 1

Answer:

1. the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
2. Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
3. Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
