Question
A spherical metallic Christmas tree ornament has a diameter of $8.00 \mathrm{~cm} .$ If Saint Nicholas is by the fireplace, $1.56 \mathrm{~m}$ away, where will he see his reflection in the ornament? Is the image real or virtual?
Step 1
The radius is given by the formula $r = \frac{d}{2}$, where $d$ is the diameter. Given that the diameter is $8.00 \, \mathrm{cm}$, we can calculate the radius as follows: \[r = \frac{8.00 \, \mathrm{cm}}{2} = 4.00 \, \mathrm{cm}\] Show more…
