Question

2) Equation of a progressive
wave is y=0.02 sin 2pi (t/0.01
-x/0.3) S.I, velocity of the
progressive wave is,​

Answer 1

Explanation:

Wavelength(λ)=

k

2π

=

2π

2π×50

=50cm

We know that path difference of λ gives rise to phase difference of 2π. So path difference of 5cm gives rise to phase difference of

λ

2π

×5=

5

π
