In Young's double slit experiment, intensity at a point is ( 1 4 ) of the maximum intensity. The angular position of this point is
Options
- A⁻¹ ( D )
- B⁻¹ ( 2 d )
- C⁻¹ ( 3 d )
- D⁻¹ ( 4 d )
Correct answer
C. ⁻¹ ( 3 d )
Step-by-step solution
For any point in interference pattern, array ll & I=I_ ^2 2 & I_ 4 =I_ ^2 2 & ^2 2 = 1 4 & 2 = 1 2 & 2 =60^ = 3 & = 2 3 array We know that, = ( 2 ) x , where x is path difference. and x = d array ll & 2 3 = 2 ( ~d ) & 3 ~d = & = ⁻¹ ( 3 ~d ) array
