16. mmh A 2.0-cm-high object is situated 15.0 cm in front of a concave mirror that has a radius of curvature of 10.0 cm. Using a ray diagram drawn to scale, measure (a) the location and (b) the height of the image. The mirror must be drawn to scale.

 

The following diagram was done by hand on paper and then scanned to be placed it.  I am including equations after to verify the drawing.  Due to being scanned and copied, it may not be exactly the correct dimensions in the electronic or printed version now.

 

 

From the Mirror equation

Solve for image distance, i

 

 

This is pretty close to the measured 7.4 cm!

We find height from

Solve for image height

 

 

The minus sign indicates image is upset down and this agrees with drawing which also got 1.0 cm!
