Paragraph for Question Nos. 15
A monochromatic point source S of wavelength l = 5000√2 Å (in air) is placed at a distance d = 1 mm below the surface of transparent liquid as shown in figure. A very large screen is placed along y-axis at horizontal distance D = 1 metre from point source. The refractive index of liquid is √2 .  ( Neglect partial reflection of rays from source S at liquid-air interface.)
Q. The y-coordinates of second order bright formed on the screen is 
  • a)
    250 mm
  • b)
    500 mm
  • c)
    -250 mm
  • d)
    -500 mm
Correct answer is option 'D'. Can you explain this answer?

The critical angle is C = 45°
Hence all rays from S which are incident on interface at an angle of incidence greater than 45° are reflected back (and appear to come from S1) and fall on screen between OP. Light also directly falls on OP from S.
So Interference pattern is formed in region OP.Since waves from S do not under go phase change during reflection, We can take S and S1 to be coherent sources in same phase. Hence zero order bright is formed at y = 0
