MHT CET 2026 Physics question
In Young's double slit experiment, width of the second slit is double the width of first slit, consequently, the amplitude of the light from two slits. '' is the maximum intensity. The resultant intensity 'I' when they interfere with the phase difference of is given by
Answer: (A)
Solution
Taking the amplitudes of the two slits as and (ratio 1 : 2, as required by the form of the options), the resultant intensity is . The maximum intensity (at ) is , so . Using $φ = 2
