Question

Two slits in Young's experiment have widths in the ratio 81 : 1. What is the ratio of the amplitudes of light waves coming from them ?
(Ans. : 9 : I)

Answer 1

Hey mate ^_^

Solution :

Width ratio w1 / w2 = I1/I2= 81 / 1

Amplitude ratio is a1/a2 = √I1/I2

=√81/1

=9:1

$\frac{w1}{w2} = \frac{l1}{l2 } = \frac{81}{1} \\ \\ \frac{l1}{l2} = \frac{ {a1}^{2} }{ {a2}^{2} } \\ \\ \frac{a1}{a2} = \sqrt{ \frac{81}{1} } = \frac{9}{1}$
