Answer -
Equation for a travelling harmonic wave is given as:
y (x, t)= 2.0 cos 2π (10t – 0.0080x + 0.35)
= 2.0 cos (20πt – 0.016πx +0.70 π)
Where,
Propagation constant, k =0.0160 π
Amplitude, a = 2 cm
Angular frequency, ω= 20 π rad/s
Phase difference is given by the relation:
(a) For x = 4 m = 400 cm
Φ = 0.016 π × 400 = 6.4 π rad
(b) For 0.5 m = 50 cm
Φ = 0.016 π × 50 = 0.8 π rad
(c) For
(d) For
