Question

The frequency of the given wave is 50Hz. Find :-
(I) Amplitude
(II) Wavelength
(III) Velocity
(all three in their SI units)​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

A.

3 cm it can be seen from the image that amp is 3cm

B.

20 cm. distance between first crest and the second one

C.

v= wf

velocity = wavelength *. frequency

= 20* 50

=1000 m/s

OR

The frequency of the wave is 50 Hz.

(A) From the given figure, it can be seen that the amplitude of the wave is 3 cm. It is equal to the maximum displacement of the wave.

(B) The distance between two consecutive crest and trough is called the wavelength. Here, the distance is 20 cm.

(C) The velocity of the wave is given by :

v = 50 m/s

Hence, this is the required solution.
