Question
wave is represented by the equation
y = a sin (0.01x - 2 t)
where a and x are in cm and t in second. Velocity of propagation of the waves is :
y = a sin (0.01x - 2 t)
where a and x are in cm and t in second. Velocity of propagation of the waves is :
Options
A.200 cm/sec
B.10 cm/sec
C.25 cm/sec
D.50 cm/sec
Solution
In the wave of the form
y = sin (ωt - kx)
Velocity v =
here ω = 2; k = 0.01
v =
= 200 cm/sec
y = sin (ωt - kx)
Velocity v =
here ω = 2; k = 0.01
v =
= 200 cm/secCreate a free account to view solution
