In diffraction experiment from single slit, the angular width of the central maxima does NOT depend upon (a) width of the slit (b) wavelength of light used. (c) ratio of wavelength and slit width. (d) distance of the slit from the screen.

Answer: (d). Angular width of central maximum = (2λ)/(a). It depends on λ, on a and on the ratio λ/a, but not on the slit-to-screen distance D. So the answer is (d).

Diffraction at a Single Slit

In diffraction experiment from single slit, the angular width of the central maxima does NOT depend upon

Show answer and solution

Answer: (d)

Angular width of central maximum $= \dfrac{2\lambda}{a}$ .
It depends on $\lambda$ , on $a$ and on the ratio $\lambda/a$ , but not on the slit-to-screen distance $D$ .
So the answer is (d).
