A3 cm tall object is 45 cm in front of a convex mirror that has a -25 cm focal length. what is the image characteristics? real / virtual upright / inverted smaller / larger / same size o a. real inverted larger ob. real upright smaller o c. vitual inverted larger o d. virtual upright smaller

Explanation:

It is given that,

Height of the object, h = 3 cm

Object distance, u = -45 cm

Focal length of the mirror, f = - 25 cm

Using mirror's formula as :

, v is the image distance

v = −56.25 cm

Let h' is the height of the image. Using the formula of magnification as :

So, the image is larger than object. The image is upright and inverted. Hence, this is the required solution.
