Question
Consider the optical system shown in figure. The point source of light S is having wavelength equals to λ . The light is reaching screen only after reflection. For point P to be 2nd maxima, the value of λ would be (D > > d and d > > λ)
Options
A.
B.
C.
D.
Solution
At P, ᐃx =
; For 2nd maxima, ᐃx = 2λ ⇒ 
= 2λ =
