Question

(b) Figure shows a snapshot of a wave-form of frequency 50Hz. For this wave motior
find (i) wavelength (ii) amplitude (iii) velocity.
(​

Answer 1

Answer:

Here, v=50Hz

(a) Wavelength = distance between two consecutive crests.

=λ=25cm−5cm=20cm

(b) Amplitude = 4cm

( c) Wave velocity, v=vλ=50×20

=1000cm/s=10m/s.
