The number is
Explanation:
From the question we are told that
The wavelength is
The length of the glass plates is
The distance between the plates (radius of wire ) =
Generally the condition for constructive interference in a film is mathematically represented as
Where t is the thickness of the separation between the glass i.e
t = 0 at the edge where the glasses are touching each other and
t = 2d at the edge where the glasses are separated by the wire
m is the order of the fringe it starts from 0, 1 , 2 ...
So
=>
=>
given that we start counting m from zero
it means that the number of bright fringes that would appear is
=>
=>
<h2>Option A is the correct answer.</h2>
Explanation:
When an elevator moves upward with consonant acceleration a, the overall acceleration on the body is given by
a' = a + g
So acceleration of pendulum is a + g.
We have equation for period of simple pendulum
In normal case a' = g here a' is more.
From the equation we can see that period of simple pendulum is inversely proportional to square root of acceleration.
Since acceleration increases period decreases.
Option A is the correct answer.
