Question

two slits in youngs experiment produce intensities in the ratio 81:1 .what is ratio of amplitude of light waves coming from them​

Answer 1

Answer:

given = two slits intensities ratio  = 81:1

to find = ratio of amplitude =?

solution :-

let w₁ and w₂ be widths

and I₁ and I₂ be intensities.

∴  W₁ / W₂ = I₁ / I₂ =81 / 1

∴  a₁ / a₂ =  =  

∴  9 : 1

∴ 9 : 1 is a ratio of their amplitudes.

Explanation:

pls mark brainiest if it helps

Answer 2

Explanation:

Two slits in Young’s experiment produce intensities in the ratio 8 : 1. What is the ratio of the amplitudes

of light waves coming from them?
