Answer 1

Hola User_______________

Here is Your Answer..!!
_______________________

↪⭐Actually welcome to the concept of the WAVE OPTICS

↪Basically we know that ....

↪W1/W2 = I1 / I2 = A1^2 / A2^2

↪so applying this we get as

↪⭐The intensity of Imax to Imin will be obtained as

↪⭐Imax/ Imin = 9 / 1

Answer 2

ASSALAMUALAIKUM,

SOLUTION:-

intensity is directly proportional to the width of the slit and also directly proportional to square of amplitude....

then,

W1/W2 = I1/I2 = A^/B^

A^/B^ = 1/4

A/B = 1/2

B = 2A

I max./ Imin.

= (A+B)^ / (A-B)^

=9/1

=9:1 watts

INSHAALLAH it will help you!
