Answer:
The value is ![\lambda = 572 *10^{-9} \ m](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%20572%20%2A10%5E%7B-9%7D%20%5C%20m)
Explanation:
From the question we are told that
The number of bright fringes is n = 402
The displacement of the mirror is ![\delta l = 0.115 \ mm = 1.15 *10^{-4} \ m](https://tex.z-dn.net/?f=%5Cdelta%20l%20%20%3D%20%200.115%20%5C%20mm%20%3D%201.15%20%2A10%5E%7B-4%7D%20%5C%20%20m)
Generally the number of fringes is mathematically represented as
![n = \frac{2 * \delta l }{\lambda }](https://tex.z-dn.net/?f=n%20%20%3D%20%20%5Cfrac%7B2%20%2A%20%20%5Cdelta%20%20l%20%7D%7B%5Clambda%20%7D)
=> ![\lambda = \frac{2 * \delta l }{n }](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%20%20%5Cfrac%7B2%20%2A%20%20%5Cdelta%20%20l%20%7D%7Bn%20%7D)
=> ![\lambda = \frac{2 * 1.15*10^{-4} }{402 }](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%20%20%5Cfrac%7B2%20%2A%20%201.15%2A10%5E%7B-4%7D%20%7D%7B402%20%7D)
=> ![\lambda = 572 *10^{-9} \ m](https://tex.z-dn.net/?f=%5Clambda%20%20%3D%20572%20%2A10%5E%7B-9%7D%20%5C%20m)
When you push a door closed it doesn't travel in a straight line it turns around the hinges this is an example of a line
A windmill produces wind without electricity. wind blows on a windmill and it and that’s how it produces wind. You can put a windmill in anywhere outdoors (ex. Deserts or plains)
