Question

A wave travelling in the +ve x-direction having displacement along y-direction as 1m, wavelength 2πm and frequency of 1π Hz is represented by


A
y=sin(x2t)
loader
B
y=sin(2πx2πt)
loader
C
y=sin(10πx20πt)
loader
D
y=sin(2πx+2πt)
loader

Solution

The correct option is A y=sin(x2t)
y=a sin(ωtkx)
OR
y=a sin(kxωt)
y=sin[x2t](1)
k=2πλ=2π2π
ω=2π.v=2π.1π=2
a=1m
