Question

if a phase difference between two points is separated by 0.25 m in a wave is 0.5 pai then what is the wavelength of a wave​

Answer 1

Answer:

Phase difference =

λ

2π

×path difference.

The phase difference between any two particles in a wave determines lack of harmony in the vibrating state of two particles ie, how far one particle leads the other or lags behind the other.

From relation

Δϕ=

λ

2π

×δx

⇒Δx=

2π

λ

×Δϕ ...(i)

Also, λ=

n

v

...(ii)

Now, from Eqs. (i) and (ii), we get

Δx=

2πn

v

×Δϕ

⇒Δx=

2π×50
