What is the mirror formula for curved mirrors?

Answer

A

1 over f is equal to the fraction with numerator 1 and denominator d sub o minus the fraction with numerator 1 and denominator d sub i

B

1 over f is equal to the fraction with numerator 1 and denominator d sub o plus the fraction with numerator 1 and denominator d sub i

C

1 over f plus the fraction with numerator 1 and denominator d sub o is equal to the fraction with numerator 1 and denominator d sub i

D

1 over f is equal to open paren the fraction with numerator 1 and denominator d sub o close paren times open paren the fraction with numerator 1 and denominator d sub i close paren

Explanation

The mirror equation relates focal length f, object distance dₒ, and image distance dᵢ as 1/f = 1/dₒ + 1/dᵢ. This is the standard mirror formula, so the correct choice is “1 over f is equal to 1/dₒ plus 1/dᵢ.”
