Question

the equation of a progressive wave is y =0.5 sin where 'x' and 'y' are in cm. and 't' is sec. speed of the wave is​

Answer 1

Answer:

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
