What gets asked: 16 concepts
Every question in the bank is tagged to one of these, so practice can target the exact idea you keep missing.
Sample questions
A single slit of width 'a' is illuminated by monochromatic light of wavelength '$\lambda$'. A diffraction pattern is observed on a screen. If the width of the central maximum on the screen is $W$, which of the following changes will result in an increase in $W$? (Assume the screen is far from the slit). The diagram shows a single slit of width 'a' illuminated by a plane wave. A screen is placed at distance D from the slit. Diffraction minima occur at angles such that $a\sin\theta = n\lambda$.
In Young's double-slit experiment, if the distance between the slits is reduced to half and the distance between the slits and the screen is doubled, the fringe width will:
In case of linearly polarized light, the magnitude of the electric field vector:
