Question

a simple harmonic wave of frequeny 20Hz is traveling along the positive x direction with the velocity of 30m/s two particles in the path if the wave 0.45 apart differ in phase by​

Answer 1

Answer:

f=5Hz

v=40m/s

as, λ=

f

v

[wavelength]

λ=

40

=8m

as, λ path difference means 2π phase difference.

∴0.8 path difference=

10

2π

phase difference

So, phase difference,
