A string is stretched along x-axis. Shape of string transferring wave at t = t 1 sec is given by y = e –2x . If wave velocity is ‘v 0 ’ in negative x-direction, then equation of waves is –
A
e –2(x – vt)
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
If shape of string at t = t 0 is given by y = f(x), the equation of wave traveling in negative x-direction will be
y(x, t) = f{x + v(t – t 0 )}.
