In Young's double slit experiment, the intensity at a point where the path difference is \( \frac{\lambda}{6} \) ( \( \lambda \) being the wavelength of the light used) is \( I \). If \( I_0 \) denotes the maximum intensity, \( \frac{I}{I_0} \) is equal to
In Young’s double-slit experiment with monochromatic light of wavelength 6000 Å, the fringe width is 3 mm. If the distance between the screen and slits is increased by 50\% and the distance between the slits is decreased by 10\%, then the fringe width is
Two light waves of intensities \( I \) and \( 2I \) superimpose on each other. If the path difference between the light waves reaching a point is 12.5% of the wavelength of the light, then the resultant intensity at the point is (Both the light waves have the same wavelength)
The minimum deviation produced by a hollow prism filled with a certain liquid is found to be 30\(^\circ\). The light ray is also found to be refracted at an angle of 30\(^\circ\). Then the refractive index of the liquid is
When a convex lens is immersed in two different liquids of refractive indices 1.25 and 1.5, the ratio of the focal lengths of the lens is 5:16. The refractive index of the material of the lens is:
A person can see objects clearly when they lie between 40 cm and 400 cm from his eye. In order to increase the maximum distance of distant vision to infinity, the type of lens and power of correction lens required respectively are:
If a slit of width \( x \) was illuminated by red light having wavelength \( 6500 \) Å, the first minima was obtained at \( \theta = 30^\circ \). Then the value of \( x \) is:
The focal length of a thin converging lens in air is 20 cm. When the lens is immersed in a liquid, it behaves like a concave lens of power 1 D. If the refractive index of the material of the lens is 1.5, the refractive index of the liquid is
