In this apparatus, we've got a reference bulb on the left. This is the bulb that we are using at the constant source of light for this experiment. On the right, we have an adjustable group of small bulbs, and a Joly Photometer. In the videos below, you can select the number of small bulbs illuminated. Then you can use the Joly Photometer and ruler to find the distance away from the reference bulb where the brightness is equal to the brightness of the group of small bulbs on the right. For example, if you select "3 bulbs" video, there will be three small bulbs illuminated on the right. You can move the Joly Photometer until the brightness from the small bulbs on the right is equal to the illumination from the reference bulb on the left. Using the ruler, we can measure the distance at which the large bulb has a brightness equal to, for example, three small bulbs. We can say "the reference bulb has a brightness equal to three small bulbs when the small bulbs are 44 cm away from the large bulb."
