Question

A light meter measures the intensity \( I \) of the light falling on it. Theory suggests that this varies as the inverse square of the distance \( d \). Which graph of the results supports this theory?

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Remember that the inverse square law applies to various physical phenomena, including gravity and light intensity.

Answer 1

The Correct Option is A

The intensity of light follows the inverse square law, which means the intensity \( I \) is proportional to \( \frac{1}{d^2} \). The graph that best represents this is the one where intensity decreases as the square of the distance increases.
