Mark the correct statement

Transparent medium bounded by two refracting surfaces in which at least one of these is curved is a property of:

A concave mirror produces $$2$$ times magnified real image of an object placed at $$5 cm$$ in front of it. Where is image located?

Mark the correct statement:

A concave mirror produces $$10$$ times enlarged image (real) of an object placed $$1 cm$$ in front of it. Where is the image located?

Magnification produced by plane mirror is $$+1$$. It means:

The focal length of a spherical mirror of radius of curvature $$40 cm$$ is

A ray of light travels from air to glass at an angle of incidence of $$37^{\circ}$$, the angle of refraction is $$24^{\circ}$$. What is the refractive index of glass?
(Given: $$\sin 37^{\circ} = 0.60, \sin 24^{\circ} = 0.40)$$

An object is placed at a distance of $$100 cm$$ from a concave lens of focal length $$40 cm$$. Find the distance of the position of image from the lens in $$cm$$.

A convex lens of focal length $$5\ cm$$ is placed at a distance of $$6\ cm$$ from a wall. How far from the lens should an object be placed so as to form its real image on the wall?
