Luminosity and brightness of an object can be used to calculate its distance
from us with the equation d=1 Ant
where d' is the distance in meters from
the object, L is the luminosity in watts (w), and b is the apparent brightness
w
measured in
If the luminosity of a lightbulb is 100 W and the brightness is
measured to be 0.01 what is the distance to the lightbulb?
m
