when reflected light rays and reflected rays are perpendicular, reflected light is polarised with electric field vector perpendicular to the plane of incidence.
Also. Brewster's law μ=tani.
Unpolarised light is incident from air on plane surface of a material of refractive index μ. At a particular angle of incident 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?

The refractive index of glass is 1.5. The speed of light in glass is:
Two thin lenses of focal lengths f₁ = +20 cm and f₂ = -10 cm are in contact. The power of the combination is:
In a certain camera, a combination of four similar thin convex lenses are arranged axially in contact. Then the power of the combination and the total magnification in comparison to the power $(p)$ and magnification $(m)$ for each lens will be, respectively
The intensity of transmitted light when a polaroid sheet, placed between two crossed polaroids at $22.5^{\circ}$ from the polarization axis of one of the polaroid, is ( $\mathrm{I}_0$ is the intensity of polarised light after passing through the first polaroid):
A microscope has an objective of focal length 2 cm , eyepiece of focal length 4 cm and the tube length of 40 cm . If the distance of distinct vision of eye is 25 cm , the magnification in the microscope is :
