Question
For the same wave (frequency 300 Hz, velocity 250 m/s), what is the phase difference between two displacements at a single point, separated in time by 10⁻² s?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The phase difference (Δφ) in time (Δt) is given by Δφ = ωΔt, where ω is the angular frequency. The angular frequency ω = 2πf.Given f = 300 Hz and Δt = 10⁻² s.ω = 2π * 300 Hz = 600π rad/s.Δφ = (600π rad/s) * (10⁻² s) = 6π radians.
Hint
The phase difference due to time separation depends on the angular frequency and time interval.
