Question

The following figure shows a wave from frequency. For this Wave Motion, find the:

(i) amplitude,

(ii) wavelength

(iii) velocity

Answer 1

Answer:

Amplitude-4 cm

wavelength-20cm

Answer 2

I) amplitude = 4 cm

II) wavelength = 20 cm

III) velocity = frequency × 0.2 m/s

From the graph it is clear that the wave is a sinusoidal wave .

Amplitude is the maximum distance from the mean position . From the graph , amplitude = 4 cm

Wavelength is equal to the distance between to consecutive troughs or crests . From the graph, wavelength = 20 cm

Velocity of the wave = wavelength × frequency

As , the frequency is not given

=> frequency × 0.2 m/s
