Question

The wave y = 10⁻⁴ sin(60t + 2x), with x and y in metres and t in seconds, represents which of the following?

G1 Physics · Accepted Answer

Step 1: Compare y = 10⁻⁴ sin(60t+2x) with y = A sin(ωt+kx). Step 2: A=10⁻⁴ m, ω=60 s⁻¹, k=2 m⁻¹, so v=ω/k=30 m s⁻¹ toward −x, λ=2π/k=π m and f=ω/2π=30/π Hz. All four statements are correct.
