A man of height 1.47 m stands on a straight road on a hot day. The vertical temperature in the air results in a variation of refractive index with height y as mu=mu_(0)sqrt((1+ay)) where mu_(0) is the refractive index of air near the road a =1.5 xx 10^(-6) /m. What is the apparent length of the road man is able to sec?

In figure, parallel beam of light is incident on the plane of the slits of a Young's double-slit experiment. Light incident on the slit S_(1) passes through a medium of variable refractive index mu = 1 + ax (where 'x' is the distance from the plane of slits as shown), up to distance 'I' before falling on S_(1) . Rest of the space is filled with air. If at 'O' a minima is formed. then the minimum value of the positive constant a (in terms of l and wavelength lambda in air) is

A biconvex thin lens of radius of curvature R is made up of variable refractive index mu=2(1+r/d) . Assume 2d lt lt R . There are infinite images of the point O, which is placed at a distance R on the principal axis from the lens as shown in the figure. The image is spread along the pricipal axis in a length of (r is the radial distance from P measured perpendicular to principal axis)

A man of height 2.0 m is standing on a level road because of temprature variation the refractive index of air is varying as mu=sqrt(1+ay), where y is height from road. If a=2.0xx10^-6 m^-1. Then, find distant point that he can see on the road.

A glass sphere having refractive index (3/2) is having a small irregularity at its centre. It is placed in a liquid of refractive index (4)/(3) such that the surface of the liquid is at a distance r above the sphere, where r = 20 cm is radius of the sphere, where r = 20 cm is radius of the sphere. If the irregularity is viewed from above then what is it's distance (in cm) from the centre where eye will observed the irregularity?

An insect of mass m, starts moving on a rough inclined surface from point A. As the surface is vert sticky, the corfficient of fricion between the insect and the incline is mu=1 . Assume that it can move in any direction, up the incline or down the incline then

A cylinder is filled with a liquid of refractive index mu . The radius of the cylinder is decreasing at a constant rate K . The volume of the liquid inside the container remains constant at V . The observer and the object O are in a state of rest at a distance L from each other. When radius of cylinder is r the apparent velocity of the object as seen by the observer is

A uniform solid sphere of radius R is in equilibrium inside a liquid whose density varies with depth from free surface as rho=rho_(0)(1+h/(h_(0))) where h is depth from free surface. Density of sphere sigma will be :

A thin equiconvex glass lens (mu_(g)=1.5) is beign placed on the top of a vessel of height h=20cm as shown figure. A luminous point source is beign placed at the bottom of vessel on the principal axis of the lens. When the air is on both the side of the lens the image of luminous source is formed at a distance of 20cm from the lens out side the vessel. When the air inside the vessel is being replaced by a liquid of refractive index mu_(l) the image of the same source is being formed at a distance 30cm from the lens outside the vessel. Find the mu_(l) .
