In a Young's double slit experiment the ...

In a Young's double slit experiment the intensity of light at each slit is `I_(0)`. Interference pattern in observed along a direction parallel to the line `S_(1) S_(2)`, on screen S.–

The minimum, maximum, and the intensity averaged over the entire screen are respectively

A

`0, 4I_(0), 2I_(0)`

B

`I_(0), 2I_(0), 3I_(0)//2`

C

`I_(0), 4I_(0), I_(0)`

D

`I_(0), 2I_(0), I_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A

`I_("max")= (sqrt(I_(0))+ sqrt(I_(0)))^(2)= 4I_(0)`
`implies I_("min")= (sqrt(I_(0))- sqrt(I_(0)))^(2)= 0`
`implies I_("avg")= I_(0)+ I_(0)= 2I_(0)`
