If the equation of transverse wave is `y=5 sin 2 pi [(t)/(0.04)-(x)/(40)]`, where distance is in cm and time in second, then the wavelength of the wave is

A

10 cm

B

25 cm

C

40 cm

D

60 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`y = sin 2pi [(t)/(0.04) - (x)/(40)]`
`k = (2pi)/(40)`
`(2pi)/(lamda) = (2pi)/(40) " " :. lamda = 40 cm`
