The focal length of a plane mirror is

May 14, 2026

The focal length of a plane mirror is infinity ((infty )). Because a plane mirror is flat and does not converge or diverge light rays to a specific pointmeaning parallel rays reflect parallel without meetingit is considered a spherical mirror with an infinite radius of curvature ((R = infty)), leading to an infinite focal length […]

The rate of production of heat

May 9, 2026

Heat is produced at a rate given by H in a resistor when it is connected across a supply of voltage V. If now the resistance of the resistor is doubled and the supply voltage is made V/3, then the rate of production of heat in the resistor will be-
