The time taken by a vibrating body to move from one extreme position to the other extreme position is 0.1 s. If the distance between adjacent crests is 2 m, write the steps to determine the wave velocity in proper sequence
(a) Determine the frequency of the wave (f)
(b) Note down the wavelength `(lamda)`
(c) Note down the time period (T)
Determine the velocity of the wave as `v = f lamda`

Options

A. a b c d
B. b c a d
C. d a b c
D. d c b a

Answer

B

Explanation

Initially the wavelength `(lamda)` is noted (b). From the time period of oscillation the frequency (f) is determined (c,a)
The velocity of the wave v is determined as velocity `v = f lamda (d)`
