Ray Optics

Find the value of the angle of emergence from the prism. Refractive index of the glass is $\sqrt{3}$?

For the given incident ray as shown in the figure, the condition of the total internal reflection of this ray and the minimum refractive index of prism will be:

A beam of light consisting of red, green and blue colours is incident on a right-angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are $1.39$,$1.44$and $1.47$…

When one light ray is reflected from a plane mirror with $30^{\circ}$ angle of reflection, the angle of deviation of the ray after reflection is:

A ray of light entering from air into a denser medium of refractive index $\frac{4}{3}$, as shown in figure. The light ray suffers total internal reflection at the adjacent surface as shown. The maximum value of angle…

A green light is incident from the water to the air - water interface at the critical angle $\left(\theta\,_{c}\right)$.Select the correct statement?

There is a small source of light at some depth below the surface of water (refractive index $=\frac{4}{3}$) in a tank of large cross sectional surface area. Neglecting any reflection from the bottom and absorption by…

The graph shows how the magnification $m$ produced by a thin lens varies with image distance $v$. The focal length of the lens used is

The distance between an object and a screen is$100\mathrm{cm}$. A lens can produce real image of the object on the screen for two different positions between the screen and the object. The distance between these two…

A compound microscope consists of an objective lens of focal length $1\mathrm{cm}$ and an eye piece of focal length $5\mathrm{cm}$ with a separation of $10\mathrm{cm}.$ The distance between an object and the objective…

An object viewed from a near point distance of$25\mathrm{cm}$, using a microscopic lens with magnification $6,$ gives an unresolved image. A resolved image is observed at infinite distance with a total magnification…

The driver sitting inside a parked car is watching vehicles approaching from behind with the help of his side view mirror, which is a convex mirror with radius of curvature $\mathrm{R}=2 \mathrm{~m}$. Another car…
