Answer:
The number of bright-dark fringe is 42
Solution:
As per the question:
Wavelength of light, 
Length of the glass cell, x = 3.73 cm = 0.0373 m
Refractive index, 
Now,
To calculate the bright-dark fringe shifts, we use the formula given below:
Now, substituting the appropriate values in the above formula:
≈ 42

Explanation:
Innovation is nothing but the use of various things such as ideas, products, people to build up a solution for the benefit of the human. It can be any product or any solution which is new and can solve people's problems.
Innovation solution makes use of technology to provide and dispatch new solutions or services which is a combination of both technology and ideas.
One such example of an innovative solution we can see is the use of "Robots" in medical science or in any military operations or rescue operation.
Sometimes it is difficult for humans to do everything or go to everywhere. Thus scientist and engineers have developed many advance robots or machines using new ideas and technology to find solutions to these problems.
Using innovations and technologies, one can find solutions to many problems which is difficult for the peoples. Robots can be used in any surveillance operation or in places of radioactive surrounding where there is a danger of humans to get exposed to such threats. They are also used in medical sciences to operate and support the patient.
