Ray Optics

Four long glass plates with refractive indices $\mathrm{n}_1>\mathrm{n}_2>\mathrm{n}_3>\mathrm{n}_4$ are stacked in parallel as shown in the figure. A light ray, traveling in the first plate, is incident on the second…

The figure shows a ray of light going from a medium of refractive index $n_1$ to a medium of refractive index $n_2$ such that $\theta_1>\theta_2$. Select the correct option.

A transparent glass slab of thickness $t=0.50 \mathrm{~cm}$ is placed with its face $A B$ on a horizontal table. A hemispherical water drop of radius $R=0.33 \mathrm{~cm}$ condenses on the glass slab as shown in figure.…

A glass prism, of angle $\beta$, is placed in front of two mutually perpendicular mirrors, as shown in the figure below. The refractive index of the material of the prism is $\left(\right.$ taking $\left.n_{\text {air…

A ray of light is incident perpendicularly at point A on a rectangular medium with different refractive indices, $n_1$ and $n_2$, in a configuration as shown schematically in the figure. The angle that the emergent ray…

Consider an optical medium where refractive index varies linearly with height i.e. $n(y)=n(0)+k y$ where $k$ is a positive constant and $y$ is the height above the ground level. Here positive number $n(0)$ is the…

A fish is 10.0 cm from the front surface of a spherical fish bowl of radius 20.0 cm , as shown in the figure. The walls of the bowl are thin, and their effects can be neglected. As observed from the point P (see…

The figure represents the circular cross section of a transparent solid cylinder of radius $R$ and refractive index $\sqrt{3}$ placed in air. A ray of light enters the cylinder parallel to the diameter FE and displaced…

A spherical glass bottle having negligible wall thickness is placed in air. When the bottle is completely filled with water, its focal length is $f$. If the water is replaced by another transparent liquid of higher…

The power of a system of two thin lenses which share a common axis and are separated by a distance $d$ is given by $P=P_1+P_2-$ $P_1 P_2 d$. Consider two thin lenses with focal lengths $f_1=30.0$ cm and $f_2=40.0…

The minimum distance, in cm, between an object and it's real image through a convex lens of focal length 10 cm is

A powerful point light source is placed at the bottom of a large pool containing water. The depth of the pool is 5 m and the refractive index of the water is 1.33 . The area (in $\mathrm{m}^2$) illuminated as viewed…
