Question

Pls pls pls... Solve que 14th​

Answer 1

Answer:

I=k/4

Explanation:

Let I1=I2=I

Let ϕ be the difference between two light waves .

Therefore the resultant intensity

IR=I+I

=2I+2I

=4I

But 4I=k

When path difference is λ3 phase difference is 2π3 radius

I′R=I+I+2I1−−√

I′R=2I+2I(−1/2)

=2I−I

=I

I=k4
