Two sources with intensity `I_(0)` and `4I_(0)` respectively, interfere at a point in a medium. Find the ratio of
(i) maximum and minimum possible intensities,
(ii) ratio of amplitudes

Explanation

To solve the problem, we need to find the maximum and minimum possible intensities and the ratio of amplitudes for two sources with intensities \( I_1 = I_0 \) and \( I_2 = 4I_0 \).

### Step-by-Step Solution:

#### (i) Finding Maximum and Minimum Intensities

1. **Maximum Intensity (\( I_{\text{max}} \))**:
The formula for the maximum intensity when two waves interfere is given by:
