Problem 34P

The distance to a point source is decreased by a factor of three, (a) By what multiplicative factor does the intensity increase? (b) By what additive amount does the intensity level increase?

Solution 34P

Step 1 of 3:

In this question, we need to find the multiplicative factor by which the intensity increases

In part b, we need to find the additive amount does the intensity level increase

It is given that the point source decreases by factor of three

Part a:
