Spherical Mirrors

A ray of light incident parallel to the principal axis of a spherical mirror retraces its path after reflection.

A real image of a point object can be formed only by a concave mirror.

The mirror equation is valid only if the aperture of the mirror is small.

A ray starting from the focus of a concave mirror becomes parallel to the principal axis after reflection.

A spherical mirror never forms an image whose size is the same as that of the object.

The focal length of a spherical mirror has a smaller magnitude than that of its radius of curvature.

To get an image larger than the object, one can use

If an incident ray passes through the centre of curvature of a spherical mirror, the reflected ray will :

A ray of light is incident on a concave mirror. If it is parallel to the principal axis, the reflected ray will

$\mathrm{f}=\frac{\mathrm{r}}{2}$ is valid

A point object is placed on the principal axis of a spherical mirror. The object-distance is

The magnification of an image formed by a spherical mirror is negative. It means, the image is

An object of size $2.0 \mathrm{cm}$ is placed perpendicular to the principal axis of a concave mirror. The distance of the object from the mirror equals the radius of curvature. The size of the image will be

An object is placed at the centre of curvature of a concave mirror. The distance between its image and the pole is

The angle of incidence is the angle between

A mirror forms a virtual image of a real object.

When a concave mirror is placed facing the sun, the sun's rays converge to a point $10 \mathrm{cm}$ from the mirror. Now, an erect, $2 \mathrm{cm}$-long pin is placed $15 \mathrm{cm}$ away on the principal axis of the mirror. If you want to get the image of the pin on a card, where would you place the card? What would be the nature and height of the image?

An object is placed at a distance of $12 \mathrm{cm}$ from a convex mirror of radius of curvature $12 \mathrm{cm}$. If the height of the object is $1.2 \mathrm{cm}$, what will be the height of the image?

An object is placed at a distance of $12 \mathrm{cm}$ from a convex mirror of radius of curvature $12 \mathrm{cm}$. Find the position of the image.

Where should an object be placed before a concave mirror of focal length $20 \mathrm{cm}$ so that a real image is formed at a distance of $60 \mathrm{cm}$ from it?
