In Young's double slit experiment the wavelength of light was changed from 7000 \AA to 3500 \AA while doubling the separation between the slits. Which of the following is not true for this experiment?
The coherence of two light sources means that the light waves emitted have
In Young's double slit experiment, the intensity of light coming from one of the slits is double the intensity from the other slit. The ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed is
The path difference between the two waves $y_{1} = a_{1}\sin \left(\omega t - \frac{2\pi x}{\lambda}\right)$ and $y_{2} = a_{2}\cos \left(\omega t - \frac{2\pi x}{\lambda} +\phi\right)$ is
A parallel beam of monochromatic light is incident normally on a slit. The diffraction pattern is observed on a screen placed at the focal plane of a convex lens. If the slit width is increased, the central maximum of the diffraction pattern will
In a single slit diffraction pattern, the distance between the first minimum on the left and the first minimum on the right is $5\mathrm{mm}$. The screen on which the diffraction pattern is displayed is at a distance of $80~\mathrm{cm}$ from the slit. The wavelength is $6000\mathrm{\AA}$. The slit width in (mm) is about
When a ray is incident on a medium of refractive index $n$ at Brewster's angle, it gets

In Young's experiment, using red light ($\lambda = 6600$ \AA), 60 fringes are seen in the field of view. How many fringes will be seen by using violet light ($\lambda = 4400$ A)?

First diffraction minima due to a single slit of width \(10^{-4}\) cm is at \(\theta = 30^\circ\). Then wavelength of the light used is
