A wave is represented by the equation
\(y=A \sin \left(10 \pi x+15 \pi t+\frac{\pi}{3}\right)\)
where x is in metre and t is in second. The expression represents
\(y=A \sin \left(10 \pi x+15 \pi t+\frac{\pi}{3}\right)\)
where x is in metre and t is in second. The expression represents
- a wave travelling in the positive x-direction with a velocity 1.5 m/s.
- a wave travelling in the negative x-direction with a velocity 1.5 m/s.
- a wave travelling in the negative x-direction having a wavelength 0.2 m.
- a wave travelling in the positive x-direction having a wavelength 0.2 m.
Answer
(D) a wave travelling in the positive x-direction having a wavelength 0.2 m.
