Adentist wants a small mirror that, when 2.40 cm from a tooth, will produce a 4.0× upright image. what must its radius of curvature be? follow the sign conventions.

The radius of curvature is 6.4 cm

Explanation:

Given that,

Object distance = 2.40 cm

Magnification = 4

We need to calculate the image distance

Using formula of magnification

Put the value into the formula

Negative sign shows the image of the object is same side of object

(b). We need to calculate the radius of curvature

Using mirror formula

Put the value into the formula

Hence, The radius of curvature is 6.4 cm.

i think the answer is tomato juice? not entirely sure though
