In single slit diffraction, when wavelength lameda increases:
Correct answer: A. Width of central maxima increases
- A. Width of central maxima increases
- B. Width of central maxima does not change
- C. Central maxima becomes brighter
- D. Width of central maxima decreases
Explanation
From the equation shown below, it is clear that wavelength is directly proportional to the distance between the central maximum to the first minima. Therefore, as the wavelength increases, pattern width increases.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
