Question

From the following graph :
Find :
(i) Wavelength
(ii) Wave velocity
(iii) Time period.

Answer 1

Answer:

where is graph brother

Answer 2

Wavelength = 3m

Wave velocity = 0.75 m/s

Time period = 4s

Explanation:

The picture is missing in the question. Please refer to the attached picture for the graph.

From the graph, we can observe that one cycle of the wave is completed within 4 seconds of time and the length of one wave is given as 3 metres.

So wave length is distance travelled by one complete cycle of the wave which is 3 metres. Time period is 4 seconds.

Frequency = 1/4

Wave velocity = f * wavelength = 1/4 * 3 = 3/4 = 0.75 ms-1
