Question
The wave equation is y where t, x and y are in second, of the metre and centimetre respectively. The speed of the wave is
Options
A.400m/s
B.100m/s
C.200m/s
D.50m/s
Solution
Given equation y = 03.0sin (314t - 1.57x)Comparing it with standard equation of wave,
y = a sin (ωt - kx)
ω = 314; k = 1.57
v =
⇒ v = 
= 200m/ sec
y = a sin (ωt - kx)
ω = 314; k = 1.57
v =
⇒ v = = 200m/ secCreate a free account to view solution
