1. What is the index of refraction of a material for which the wavelength of light is 0.83 times its value in a vacuum?

2. A diffraction grating has 2400 lines per centimeter. At what angle in degrees will the third-order maximum be for 636 nm wavelength light?

3. What is m for the highest-order maximum for 462 nm light falling on double slits separated by 19.5 μm? Remember, m can only be an integer.

Plz answer all, don't have money for more questions. will give thumbs up in appreciation :)

Reflection and Refraction of Light In this activity, the properties of reflection and refraction of light will be explored. The simulation shows the light rays as they are incident on a medium interface (incident ray), the reflected from the medium interface (reflected ray), and refracted into the second medium after crossing the interface (refracted ray). Additionally the angles made by each of these rays with respect to the normal (vertical black perpendicular to the interface) are displayed as wedges in...
