A concave mirror with a focal length of 5 cm

October 18, 2019 in /by

Question 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 5 cm  forms an image of a small object placed 13 cm  in front of the mirror. Where will this image be located? (For spherical mirrors, positive p means the image is on the same side of the […]
