An unpolarised light beam strikes a glass surface at Brewster's angle. Then
Two transparent media. A and B are separated by a plane boundary. The speed of light in those media are 1.5 × 108 m/s and 2.0 × 108 m/s, respectively. The critical angle for a ray of light for these two media is:
A light ray falls on a glass surface of refractive index √3, at an angle 60°. The angle between the refracted and reflected rays would be:
Unpolarised light is incident from air on a plane surface of a material of refractive index ‘μ’. At a particular angle of incidence ‘i’, it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation ?
An astronomical refracting telescope will have large angular magnification and high angular resolution, when it has an objective lens of
The refractive index of the material of a prism is $\sqrt{2}$ and the angle of the prism is $30^{\circ}$. One of the two refracting surfaces of the prism is made a mirror inwards, by silver coating. A beam of monochromatic light entering the prism from the other face will retrace its path (after reflection from the silvered surface) if its angle of incidence on the prism is
The angle of incidence for a ray of light at a refracting surface of a prism is $45^{\circ}$. The angle of prism is $60^{\circ }$. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are :
Which of the following is not due to total internal reflection?
A convex lens is dipped in a liquid whose refractive index is equal to the refractive index of the lens. Then its focal length will
