An object is placed at a distance u from a concave mirror and its real image is received on a screen placed at a distance of v from the mirror. If f is the focal length of the mirror, then the graph between 1/v versus 1/u is

An object is placed at a distance u from a concave mirror and its real image is formed on the screen placed at distance v from the mirror. If f is the focal length of the mirror, then the graph between frac(1)(v) versus frac(1)(u) is (magnitude only)

An object is placed at a distance of 30 cm from a concave mirror and its real image is formed at a distance of 30 cm from the mirror. The focal length of the mirror is

An object is placed at a distance of 30 cm from a concave mirror and its real image is formed at a distance of 30 cm from the mirror. The focal length of the mirror is

An object is placed at a distance X_1 from the focus of a concave mirror, Its real image is formed at a distance X_2 from the focus, Show that the focal length of the mirror is sqrt(x_1x_2)

An object is placed at a distance u cm from a concave mirror of focal length f cm. The real image of the object is received on a screen placed at a distance of v cm from the mirror. The values of u are changed and the corresponding values of v are measured. Which one of the graphs shown in the figure represents the variation of 1/v with 1/u ?

An object is placed at a distance of 25 cm from a concave mirror and a real image a formed by the mirror at a distance of 37.5 cm. The focal length of the mirror is
