In Young's double slit experiment, interference pattern is found to have an intensity ratio between bright and dark fringes as 9. Then amplitude ratio will be |
1 2 9 3 |
2 |
$a_{max}=a_1+a_2;\,a_{min}=a_1-a_2$ $∴\frac{I_{max}}{I_{min}}=\frac{(a_1+a_2)^2}{(a_1-a_2)^2}=\frac{9}{1}⇒a_1=2$ and $a_2=1$ $∴\frac{a_1}{a_2}=\frac{2}{1}=2$ |
