Unformatted text preview: -10 cm. What is the image height? Correct answer: 6. Explanation: Let : o = 15 cm , i =-6 cm , and h = 15 cm . From the mirror equation, we ±rst get the image position. 1 o + 1 i = 1 f . Solving for i yields i = f o o-f = (-10 cm) (15 cm) (15 cm)-(-10 cm) =-6 cm . The magni±cation is given by M =-i o . Hence, the image height is given by H = h M = (15 cm) p--6 cm 15 cm P = 6 cm ....
