In a Young's double-slit experiment, the intensity ratio of maxima and minima is infinite. The ratio of the amlitudes of two sources

Options

A. is infinity
B. is unity
C. is two
D. can not be predicted

Answer

B

Explanation

`(I_("max"))/(I_("min"))=((a_(1)+a_(2))^(2))/((a_(1)-a_(2))^(2))`. If `a_(1)=a_(2)` then
`(I_("max"))/(I_("min"))=oo :. (a_(1))/(a_(2))=1`
