Given a double slit apparatus with slit distance 2 mm, what is the theoretical maximum number of bright spots that I would see when I shine light with a wavelength 500 nm on the slits

The values is  

Explanation:

From the question we are told that

    The slit distance is  

    The  wavelength is  

At the first half of the screen from the central maxima

   The number of bright spot according to the condition for constructive interference is  

For maximum number of spot

So  

Now for the both sides plus the central maxima  we have

substituting values

false

explanation:

boats, things on boats luggage are way more heavy then water.

compass can be used day and night, cloudy or sunny
