Two identical coherent sources of wavele...

Two identical coherent sources of wavelength `lambda` are placed at `(100 lambda, 0)` and `(-50 lambda, 0)` along x-axis. The number of maxima and minima detected are ,respectively [include origin and `(5 lambda, 0)]`

A

51 and 50

B

101 and 100

C

49 and 50

D

50 and 49

Text Solution

Verified by Experts

The correct Answer is:
b
If the detector move by `0.5 lambda` from origin, it observers 2nd maxima. So, after every `0.5 lambda`, one maxima will be observed.
