What will be the ratio of slit widths if the amplitudes of the light waves emerging from them is `sqrt(3) : 1` ?

Text Solution

AI Generated Solution

To solve the problem of finding the ratio of slit widths given the amplitude ratio of light waves emerging from them, we can follow these steps: ### Step 1: Understand the relationship between amplitude and intensity The intensity \( I \) of a wave is directly proportional to the square of its amplitude \( A \). This can be expressed as: \[ I \propto A^2 \] ...
