Answer:
I = 3.785 W/m²
Explanation:
given,
distance from the light, r = 1.45 m
Power of bulb = 100 W
The area is that of a sphere with a radius equal to the distance from the light bulb.
The formula for the area of a sphere of radius 1.45 meters is:
A = 4 π r²
A = 4 x π x 1.45²
A = 26.42 m²
Intensity of the light is equal to
I = 3.785 W/m²
Intensity of the light at 1.45 m is equal to I = 3.785 W/m²
