- Homework Statement
- A plane wavefront (wavelength = ) is falling on YDSE apparatus as shown in the
figure. The lower half of it is filled with water (refractive index = 1.5) How many
maximas can be theoretically obtained on the screen if d = 98lambda and D = 20000lambda
(include the maxima at infinity, assume coherence length to be infinite)
- Relevant Equations
- All i know is y coordinate of nth maxima is y=(n* lambda* D)/d,
where D= Distance between source and slits
and d=distance between slits
I honestly do not have any idea regarding this sum.
Any help will be appreciated:)
