Answer 2

The phase difference for interval 1 second is  ΔΦ = 4 rad  and fro distance 10 cm is  ΔΦ = 0.2 rad

Explanation:

(a) ΔΦ  = (2π / T)Δt

but 2π / T = ω = 4.0 rad/s

:. ΔΦ = ωΔt = (4.0)(1.0)

ΔΦ = 4 rad

ΔΦ = (2π / λ) Δx

but 2π / λ = k = 0.02 cm−1

ΔΦ = (0.02)(10)

ΔΦ = 0.2 rad

Hence the phase difference for interval 1 second is  ΔΦ = 4 rad  and fro distance 10 cm is  ΔΦ = 0.2 rad
