You perform a double‑slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.05 mm and place your screen 8.91 m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.97 cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength expressed in nanometers?

The wavelength is

Explanation:

From the question we are told

       The slit spacing is

       The distance from the screen

       The distance from central bright fringe

       The order of the bright fringe

Generally the position of a bright  fringe is mathematically represented as

            Where   is the wavelength

             Making the subject

substituting  value

another example of kinetic energy would be,

kinetic energy   >     moving energy
