A ray of light in liquid of refractive index 1.4, approaches the boundary surface between the liquid and air at an angle of incidence whose sine is 0.8. Which of the following statements is correct about the behaviour of the light?

A certain prism is found to produce a minimum deviation ao $38°$. It produces a deviation of $44°$ when the angle of incidence is either $42°$or $62°$. What is the angle of incidence when it is undergoing minimum deviation?

A ray incident at an angle $53°$ on a prism emerges at an angle $37°$ as shown. If the angle of incidence is made $50°$, which of the following is a possible value or the angle of emergence?

A man of height $170\mathrm{cm}$ wants to see his complete image in a plane mirror(while standing), . His eyes are at a height of $160\mathrm{cm}$ from the ground.

Two plane mirror at an angle such that a ray incident on a mirror undergoes a total deviation of $240°$after two reflections:

If the equation of mirror is given by $\mathrm{y}=2/\mathrm{\pi } \mathrm{sin\pi x} \left(\mathrm{y}>0,0\le \mathrm{x}\le 1\right)$  then find the point on which horizontal ray should be incident so that the reflected ray become perpendicular to the incident ray

Two lenses in contact made of materials with dispersive powers in the ratio $2:1$, behaves as an achromatic diverging lens of focal length $10 \mathrm{cm}$. The individual focal lengths of the lenses are:

A circular planar wire loop is dipped in a soap solution and after taking it out, held with its plane vertical in air. Assuming the thickness of the film at the top is very small, as sunlight falls on the soap film, $\&$ observer receive reflected light.
