I=w/12.6r^2 where I is the intensity of light, w is the wattage of the light bulb and r is the distance to the light bulb. Let w=100 watts and r=2 meters. Find the intensity of the light bulb

2.0491 watt per meter square

Step-by-step explanation:

We are given the following in the question:

The intensity of light is given by:

where W is the wattage of the light bulb and r is the distance to the light bulb.

We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.

Putting values, we get,

Thus, the intensity of light bulb is 2.0491 watt per meter square.
