1. The light with the wavelength 500nm propagates through themedium with index of refraction 2.5. Find the speed and thefrequency of the light in the medium.
(Answer: 1.2*10^8m/s; 6*10^14 1/s)
2. A diffraction grating is illuminated with light if wavelength500nm. It produces the first minimum at 45 degree. Find the numberof lines(slits) per mm of diffraction grating.
(answer: 1414 lines/mm)
3. A double spit experiment is performed with light of wavelength600nm. A very wide viewing screen is 2 m behind the grating. Whatis the distance between the two m=2 bright fringes on the screen?The slit separation is 0.1 mm.
(answer: 48 mm)
Thank you so much and please show me step by step
