Image formation in concave and convex mirrors

A ............... mirror is made by silvering the ............... surface of a piece of a hollow sphere.

• convex, outer

• plane, outer

• concave, outer

• concave, inner

A ............... mirror is made by silvering the ............... surface of a piece of a hollow sphere.

• concave, inner

• convex, inner

• convex, outer

• None of the above

The focus of a concave mirror is a point on the ............... through which the light rays incident ............... to the principal axis pass after reflection from the mirror.

• centre of curvature, perpendicular

• principal axis, parallel

• principal axis, perpendicular

• aperture, parallel

A concave mirror has a ............... focus, whereas a convex mirror has a ............... focus.

• real and virtual, real

• real, virtual

• virtual, real

• virtual, real and virtual

For an incident ray directed towards center of curvature of a spherical mirror, the reflected ray:

• retraces it's path

• passes through the focus

• passes through the pole

• becomes parallel to the principal axis

For a concave mirror, when the object is at infinity, the nature of the image formed at focus is

• virtual, inverted

• virtual, diminished to a point

• real, enlarged, inverted

• real, inverted, diminished to a point

For a concave mirror, when the object is at the centre of curvature, the place and nature of the image formed is :

• at focus, real, inverted

• at focus, virtual, inverted

• at centre of curvature, real, inverted, diminished

• at centre of curvature, real, same size as that of the object

For a concave mirror, when the object is at focus, the size of the image formed is:

• magnified

• highly magnified

• diminished

• of the same size

The image formed by a convex mirror is:

• erect and diminished

• erect and enlarged

• inverted and diminished

• inverted and enlarged

For a convex mirror, when the object is in front of the mirror, the image formed is :

• real, upright and magnified

• real, inverted and diminished

• virtual, upright and magnified

• virtual, upright and diminished
