Hi! In terms of magnesium fluoride what is the minimum thickness of mag fl coating that must be applied to a glass lens to make it non-reflecting for that wavelength? (the index of refraction of magnesium fluoride is intermediate to that of air and glass) 1/2 wavelength out of phase to...

[SOLVED] On The Nature Of Light The decision to define a photon as a sub-atomic particle is a difficult one to understand. According to the existing theory there is a different photon for every frequency in the whole of the electro-magnetic spectrum and for every possible combination of...

If sunlight of color B is scattered through an angle 16 times greater than sunlight of color A, then the wavelength of color B is? Dx :wink:

Hello, A monochromatic light is incident on a Youngs double spilt setup that has a slit separation of 30um. the resultant bridge fringe separation if 2.15cm on a 1.2 m from the double slit. what is the separation between the 3rd order bright fringe and the 0th order bright fringe? I know...

Hello, In a double slit experiment the slit separation is 2.0mm and two wavelengths 750nm and 900nm illuminate the slits. A screen placed 2m from the slits. at what distance from the central maximum on the screen will a bright fringe from one pattern first conincide with a bright fringe from...
