Light Reflectio...

A ray of light from air suffers partial reflection and refraction at the boundary of water as shown in the figure. In Fig, which of the ray is the correct refracted ray?

An object kept on the principal axis and infront of a spherical mirror, is moved along the axis itself. Its lateral magnification m is measured, and plotted versus object distance |u| for a range of u, as shown in fig. The magnification of the object when it is placed at a distance 20 cm in front of the mirror is:

A ray of light is incident at the glass-water interface at an angle i. It merges finally parallel to the surface of water. Then, the value of $$\mu_g$$ would be :

An object is kept at $$15\ cm$$ from a convex mirror of focal length $$25\ cm$$. What is the magnification?

Fig shows an object and its image formed by a thin lens. Then the nature and focal length of lens is

The diagram alongside shows the refraction of a ray of light from air to a liquid. The refractive index of liquid with respect to air is :

A fish is looking at a $$1.0m$$ high plant of the edge of the pond. Will the plant appear shorter or taller than its actual height, to the fish 

In the given figure, name the ray which represents the correct path of light while emerging out through a glass blocks :

The incident ray, the _______ ray and the normal lie in the same plane during refraction.

A ray of light passing through the .......... of the lens, passes on undeviated.
