Question

Which of the following is not a factor in the illuminance at a center point in a room with no windows? A. The Shape of the room. B The time of day. C The Number of lamps in the room. Choice D is incorrect ( the amount of light reflected from the ceiling)

Answer 1

The time of day ^-^because there are no windows, no other light can get inside the room.

Answer 2

B. The time of day.

Step-by-step explanation:

The time of day is not a factor in the illuminance at a center point in a room, because there's no windows.

A really important factor about illuminance is windows, because they allow sunlight to pass through and reach the room. Actually, big windows are mostly preferred because that way people can spend less electricity. So, if we have no windows, it's no important to consider them as a factor in the illuminance of a room.
