If one of the slit of a standard Young's double slit experiment is covered by a thin parallel sided glass slab so that it transmits only one-half the light intensity of the other, then

Options

A. the fringe pattern will get shifted toward the covered slit
B. the fringe pattern will get shifted away from the covered slit
C. the fringe pattern will become less bright and the dark ones will become more bright
D. the fringe width will remain unchanged

Answer

a.,c.,d

Explanation

`I_(max) = (sqrtI_(1) + sqrtI_(2))^(2) = (sqrtI_(1) + sqrt((I)/(2)))^(2) lt 4I`
`I_(min) = (sqrtI_(1) - sqrt((I)/(2)))^(2) gt 0`
