What is the equation for the reflection of light from a convex mirror?

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} – \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} – \frac{1}{u} = \frac{1}{f}$

What is the equation for the reflection of light from a concave mirror?

$\frac{1}{v} + \frac{2}{u} = \frac{1}{f}$

$\frac{1}{v} – \frac{2}{u} = \frac{1}{f}$

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} – \frac{1}{u} = \frac{1}{f}$
