Question

A vehicle side mirror is approximated as a convex mirror with f=−25f = -25  cm. A motorcycle is 100100  cm from the mirror and 120120  cm tall. What combination correctly gives image distance, magnification, and image height?

Accepted Answer

di=−20d_{i}=-20 cmm=+0.20m = +0.20 hi=+24h_{i}=+24 cm

Answer

di=−80d_{i}=-80 cmm=+0.80m = +0.80 hi=+96h_{i}=+96 cm

Answer

di=+20d_{i}=+20 cmm=−0.20m = -0.20 hi=−24h_{i}=-24 cm

Answer

di=+80d_{i}=+80 cmm=−0.80m = -0.80 hi=−96h_{i}=-96 cm
