A transverse wave propagating along x-axis is represented by:
\(y(x, t)=80 \sin \left(0.5 \pi x-4 \pi t-\frac{\pi}{4}\right)\) where, x is in meters and t is in seconds. The speed of the wave is:
- \(4 \pi \mathrm{~m} / \mathrm{s}\)
- \(0.5 \pi \mathrm{~m} / \mathrm{s}\)
- \(\frac{\pi}{4} m / 5\)
- 8 m/s
Answer
(D) 8 m/s
