Width of two slits in an interference arrangement are in the ratio 9 : 1. What is the ratio of amplitude and intensities of light wave from them?

Explanation

To solve the problem of finding the ratio of amplitudes and intensities of light waves from two slits with widths in the ratio of 9:1, we can follow these steps:

### Step-by-Step Solution

1. **Understanding the Relationship Between Intensity and Width**:
We know that the intensity (I) of light is directly proportional to the width (w) of the slit. Therefore, we can express this relationship as:
\[
\frac{I_1}{I_2} = \frac{w_1}{w_2}
