Width of two slits in Young's double slits experiment are in the ratio 9 : 4. The ratio of the amplitudes of light waves through them would be: |
2 : 1 4 : 9 2 : 3 3 : 2 |
3 : 2 |
The correct answer is Option (4) → 3 : 2 In young's double slit experiment, $I∝A^2$ $⇒\frac{I_1}{I_2}=\frac{9}{4}$ [Given] $∴\frac{A_1}{A_2}=\sqrt{\frac{I_1}{I_2}}=\frac{3}{2}$ |
