Formula lens 1/d + 1/f = 1/F; d = 32 cm, F = 14 cm; f = Fd/(d - F) = 14cm·32cm/18cm = 24.89 cm

The equation connecting s, p, and f for a simple lens can be employed for spherical mirrors, too. A concave mirror with a focal length of 7 cm forms an image of a small object placed 11 cm in front of the mirror. Where will this image be located?12/17/20
