Question

3.
The period of a periodic wave is 0.01 s. At a particular position, there is a cret att - 0. A to
appears at this position att ?
(A) 0.01 s
(B) 0.005s
(C) 0,015 s
(D) 0.025
​

Answer 1

Answer:

0.01 s

Explanation:

T=0.2s

T=0.2sat t=0

T=0.2sat t=0there is a crest, and the figure of wave which represent the following data.

T=0.2sat t=0there is a crest, and the figure of wave which represent the following data.We know from the question that next crest will occur 0.02s. And hence, the trough occur at the mean of two creast i.e.
