The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double-slit experiment is

A

infinite

B

five

C

three

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B

`dsintheta=nlamdaimpliesn=(dsintheta)/(lamda)=(2lamdasintheta)/(lamda)=2sintheta`
`impliesn_(max)=2`
`implies` Maximum number of possible Interference maxima `=(2n_(max)+1)=5`
