A biconvex lens with equal radii of curvature $R$ has a focal length $f$. If the refractive index of the lens is $\frac{3}{2}$, the focal length of the lens is
The refractive index of the material of a glass prism of refracting angle \(60^\circ\) and angle of minimum deviation \(30^\circ\) is
An object is placed at 30 cm from a convex lens of focal length 20 cm. If the object is moved towards the lens by 5 cm, then the image is shifted by}
When a beam of white light enters into an optical prism, the most deviated colour is ________.
Mobility \( \mu \) of an electron is related to average collision time \( \tau \) as: \[ \mu = \frac{e \tau}{m} \] (where \( e \) is the electronic charge, and \( m \) is the mass of the electron)
Whenever light travels from rarer medium into denser medium its
An object is placed at 10 cm in front of a concave mirror. If the image is at 20 cm from the mirror on the same side of the object, then the magnification produced by the mirror is
The apparent depth of a needle lying in a water beaker is found to be 9 cm. If water is replaced by a liquid of refractive index 1.5, then the apparent depth of needle will be (μ of water is 4/3)
The emergent ray of light after refraction at a rectangular glass slab
The refractive indices of glass and water with respect to air are $\frac{3}{2}$ and $\frac{4}{3}$ respectively. Then the refractive index of glass with respect to water is
Two plane wavefronts of light, one incident on a thin convex lens and another on the refracting face of a term prism. After refraction at them, the emerging wavefronts respectively become
