Two identical radiators have a separation of d = λ λ /4, where λ λ is the wavelength of the waves emitted by either source. The initial phase difference between the sources is π π /4. Then the intensity on the screen at a distance point situated at an angle θ θ = 30 0 from the radiators is (here I 0 is the intensity at that point due to one radiator)
Text Solution
Verified by ExpertsThe correct answer is:
A
Initial phase difference 
; Phase difference due to path difference 
where 
⇒ ⇒ 
Hence total phase difference 
.
By using
