The inverse square law can be proven in a lab for the intensity of light from a spherical light source. This law states that the intensity of light is inversely proportional to the square of the distance from the source. This means that as you move away from the light source, the intensity of light decreases rapidly.

Here are the steps to prove this:

1. Set up a spherical light source in a dark room. Make sure the light source is at a known height and is the only source of light in the room.

2. Measure the intensity of light at various distances from the source using a light meter. Record the distance and corresponding light intensity.

3. Plot the measured light intensity against the square of the distance from the source on a graph.

4. The resulting graph should show a curve that decreases as the distance increases, demonstrating the inverse square law.

So, the correct answer is b. Intensity of light from a spherical light source.
