List of top Physics Questions on Spherical Mirrors asked in AP EAPCET

A dentist uses a mirror of focal length \(24\,\text{mm}\). He views a cavity in the tooth of a patient by holding the mirror at a distance of \(16\,\text{mm}\) from the cavity. The magnification is

An object placed in front of a concave mirror at a distance of $x\text{ cm}$ from the pole gives a 3 times magnified real image. If it is moved to a distance of $(x + 5)\text{ cm}$, the magnification of the image becomes 2. The focal length of the mirror is:

The focal length of a spherical mirror made of steel is $150 \,cm$. If the temperature of the mirror increases by $200\, K$, its focal length become (coefficient of linear expansion of steel $\alpha=12 \times 10^{-6 \circ} C ^{-1} .$ )
