Q. A wave is represented by the equation $y = 0.5\sin{(10t - x)m.}$ It is a travelling wave propagating along the $+ x$ direction with velocity
A) $10\ m/s$
B) $20\ m/s$
C) $5\ m/s$
D) None of these
Explanation
(a) The velocity of wave
$v = \frac{\omega(Co - efficient\ of\ t)}{k(Co - efficient\ of\ x)} = \frac{10}{1} = 10\ m/s$
