Question
The displacement y of a particle in a medium can be expressed as y = 10-6 sin(100t + 20x + π/4)m, where t is in seconds and x in meter. The speed of the wave is
Options
A.2000 m/s
B.5 m/s
C.20 m/s
D.5π m/s.
Solution
Equation of Y = A Sin(ωt + kx)
v = 
= 5 ms-1
= 5 ms-1Create a free account to view solution
