A concave mirror has a radius of curvature of 26.0 cm. An object that is 2.4 cm tall is placed 30.0 cm from the mirror. a. Where is the image position? b. What is the image height?

Solution

VerifiedIn this problem, we have a concave mirror, and we need to find the position of the image (part $a$), and the height of the image (part $b$). We are going to use two equations, the mirror equation $\frac{1}{f} = \frac{1}{d_{o}}+ \frac{1}{d_{i}}$ where $f$ is the focal length of mirror, $d_{o}$ is the position of our object, and $d_{i}$ is the position of image. Also, we need to find the focal length of the mirror, and for that we use the equation $f=\frac{r}{2}$ Furthermore, we are going to use the magnification equation to find the image height $M= -\frac{d_{i}}{d_{o}}= \frac{h_{i}}{h_{o}}$
