The optimum pinhole diameter for a camera box with a length of 10 centimeters is 0.446 mm
<h3><u>Solution:</u></h3>Given that,
<h3><u>The optimum diameter d (in millimeters) of the pinhole in a pinhole camera can be modeled by:</u></h3>where l is the length (in millimeters) of the camera box
<h3><u>Find the optimum pinhole diameter for a camera box with a length of 10 centimeters</u></h3>l = 10 cm
We know that,
10 cm = 100 mm
<em><u>Therefore, plug in l = 100 in given formula</u></em>
Thus the optimum pinhole diameter for a camera box with a length of 10 centimeters is 0.446 mm
