Part A
We can estimate the number of photons in a room
using the following reasoning: The intensity of the
sun's rays at the earth's surface is roughly
1000 W/m? A typical room is illuminated by
indirect light or by light bulbs so that its light
intensity is some fraction of that value.
Assume that on a bright day the light intensity in the room is about one-third of what it is outside. Estimate the
intensity of the light that enters the room.
Express your answer with the approptiate units.
