A point object is situated at a distance of 30 cm from a convex mirror having a focal length of 30 cm . The image will be formed at

Step-by-step solution

Using the mirror formula, 1 v + 1 u = 1 f For a convex mirror, focal length f = +30 cm . Object distance u = -30 cm . Substituting the values, we get: 1 v + 1 -30 = 1 30 1 v = 1 30 + 1 30 = 2 30 = 1 15 v = +15 cm The positive sign indicates that the image is formed 15 cm behind the mirror.
