Asked in NEET 2006 · Wave parameters from the equation
Given: y=8.0 sin (0.5π x-4π t-π/4).
Idea: read k and ω off the equation; the speed is their ratio.
k=0.5π m⁻¹, so λ=(2π)/(0.5π)=4 m.
ω=4π rad s⁻¹, so T=(2π)/(4π)=0.5 s and f=2 Hz.
v=ω/k=fλ=2×4.
v=8 m/s.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
