3. The bright fringe of width 0.6 mm is obtained at the screen placed at a distance of 2.0.m
using light of wavelength 4000 Å in Young's experiment. If the whole apparatus is immersed in a
quid of refractive index 1.5, find out the fringe width.

➤ How to solve ?

A Force is a push / pull upon an object resulting from the people interaction with any of the another object.

Newton's 2nd law stated as F = Ma

Means,

•F acting on an object is equal

⠀⠀⠀⠀⠀to the mass of an object time it's A.

➤ Solution :

As , F = ma

➨ a = F / m

➨ 2 = F / m

Now , we want to see the value of a produced with 3f respectively

➨ a = F / m

➨ a = F / m/ ²

➨ a = 6 F / m

As we have already got F / m = 2

➨ 1 / 6 a = 2

➨ a = 12 m/s ²

⁖ New Acceleration is 12 m/s ²
