- Can you make sure you have the right answer???A diffraction grating with a width of 2.2 cm contains 1050 lines/cm across that width. For an incident wavelength of 610 nm, what is the smallest wavelength difference this grating can resolve in the second order? Number UnitsWhy are the two-source interference equations not valid for light from an incandescent bulb that shines onto a screen with a single slit, and then the light shines onto a screen with two slits in it and the light from the two slits finally shines onto a nearby screen? not monochromatic sources incoherent sources observed from a distance similar to or smaller than the separation between the sources Why are the two-source interference equations not valid for light from an incandescent bulb that shines onto a screen with a single slit, and then the light shines onto a screen with two slits in it and the light from the two slits finally shines onto a nearby screen? not monochromatic sources incoherent sources observed from a distance similar to or smaller than the separation between the sources 1 only 2 only 3 only 1 and 2 only 1 and 3 only 2 and 3 only all three
- Nonreflective coatings on camera lenses reduce the loss of light at the surfaces of multilens systems and prevent internal reflections that might mar the image. Find the minimum thickness of a layer of magnesium fluoride (n = 1.38) on flint glass (n = 1.66) that will cause destructive interference of reflected light of wavelength 509 nm near the middle of the visible spectrum. nm1. Analysis of an interference effect in a clear solid shows that the wavelength of light in the solid is 330 nm. Knowing this light comes from a He-Ne laser and has a wavelength of 634 nm in air.
