1. Suppose you are holding a flat mirror and standing at the center of a giant clock face built into the floor.
Someone standing at 12 o'clock shines a beam of light toward you, and you want to use the mirror to
reflect the beam toward you, and you want to use the mirror to reflect the beam toward an observer
standing at 5 o'clock. What should the angle of incidence be to achieve this? What should the angle of
reflection be?​

Explanation:

There are twelve marks on a clock.

There are 360 degrees on a clock face.

So therefore, 360/12 = 30 degrees.

No angle between 12 and 5 is 30 *5 = 150 degrees.

So your angle of incidence should be 150 degrees to reflect the light at 5.

And angle of incidence = angle of reflection. So angle r = 150 as well.
