Question

32. If the two slits in Young's experiment have widths in
a ratio 1:16, the ratio of intensities at the maxima
and minima in the interference pattern is: with formula ​

Answer 1

Answer:

As, Intensity ∝ width of slit (w)

Also, Intensity ∝ square of amplitude

∴w1w2=I1I2=a2b2=14

or ab14−−√=12orb=2a.

∴ImaxImin=(a+b)2(a−b)2=(a+2a)2(a−2a)2=91
