Ten questions. The result tells you which lessons you may skip.
A plane wavefront in air meets glass (\(\mu = 1.5\)) at an angle. While one end of the front travels BC in air, the wavelet from the other end grows in the glass to a radius AD. Which is true?
A line emitted at \(500\,\text{nm}\) by a galaxy is seen at \(505\,\text{nm}\). The galaxy is
For light of \(600\,\text{nm}\), a path difference of \(150\,\text{nm}\) gives a phase difference of
Two separate bulbs lighting one screen give no fringes because
Two coherent waves have amplitudes in the ratio \(3 : 4\). The ratio \(I_{\max}/I_{\min}\) is
In a double slit experiment \(\lambda = 600\,\text{nm}\), \(d = 1\,\text{mm}\) and \(D = 1\,\text{m}\). The fringe width is
With a fringe width of \(0.6\,\text{mm}\), the third dark fringe lies from the centre at
With a fringe width of \(0.6\,\text{mm}\), the intensity falls to half of \(I_{\max}\) at a distance from the centre of
A fringe width of \(0.6\,\text{mm}\) in air becomes, with the apparatus under water (\(\mu = \tfrac43\)),
A glass slab (\(\mu = 1.5\)) \(6\,\mu\text{m}\) thick covers one slit, with \(d = 1\,\text{mm}\) and \(D = 1\,\text{m}\). The pattern moves
