Diffraction at a Single Slit
In a single slit diffraction pattern, identify the incorrect statement from the following.
Show answer and solution
Answer: (d)
- Central maximum is twice as wide as the secondary maxima, so fringe widths are unequal.
- Intensity of secondary maxima falls off rapidly, so intensities are unequal.
- Hence "equal width and equal intensity" is false.
- So the incorrect statement is (d).
