A barber wants to set up a salon in a room measuring length of 3m by 3m. He has a simple wooden chair, 3 large mirrors and one bulb.

Using the knowledge of shadows and reflection, advise the barber on how to arrange a good salon using the only items he has.

Without adding more sources of light, how can he enhance the lightning in his salon.

Answer 1

He should place two mirrors at the front of the bulb fixed above the mid-level of the mirrors and a third mirror opposing the previous two mirrors.
