Which formula can be used to express the law of conservation of momentum, where p=momentum
2 answers:
Explanation :
The momentum of an object is defined as the product of its mass and the velocity with which it is moving.
The law of conservation of momentum states that the total momentum of a system remains conserved when the external force acting on it is equal to zero.
Mathematically, it can be written as :
where,
and
are the initial and the final momentum.
Hence, it is the required solution.

Explanation:
In case of Single Slit, diffraction will occur.
Then In Single slit Diffraction, width of central fringe is
where D= distance b/w screen and slit
a= slit width
\lambda = wavelength
Thus if Screen width increases keeping other factors same then width of central fringe becomes narrower as
On increasing the slit width the central bright fringe width The width of the central bright fringe becomes narrower.
