Answer :

The focal length of the makeup mirror is 0.588 meters or approximately 58.8 centimeters.

What is the focal length of makeup mirror?

To find the focal length of a makeup mirror that has a power of 1.70 D (diopters).

We can use the following formula:

f = 1/P

where f is the focal length in meters and P is the power in diopters.

Substituting P = 1.70 D into the formula, we get:

f = 1/1.70 D

f = 0.588 m

Therefore, the focal length of the makeup mirror is 0.588 meters or approximately 58.8 centimeters.

This means that light rays entering the mirror will converge at a distance of 0.588 meters behind the mirror's surface
