- Brightness as function of time.

- Relevant Equations
- See solution.

Problem:

Attempt at solution:

So "energy passing through per unit area per unit time" is equal to $$I = \frac{E_i}{A t}$$

So for a the graph will be in the form of ##y=1/x##?

For b) do we have to solve the differential equation $$dI = \frac{E_i}{A dt}$$?
