We use the equation λ = d sinθ / n
where λ is the wavelength
d is the grating spacing
θ is the angle
n is number of grating we take
First θ must be calculated using tan-1 (33/100) = aproxx 32 degree .
Now λ = d sinθ / n
= 500000* sin (32) / 1
= 2757.13 cm
λ = 275 nm

3. (25 points) The figure below depicts a laboratory setup for grating experiments. The diffraction grating has 5000 lines/cm and is 1.00m from the slit which is illuminated with sodium light. On either side of the slit, and parallel to the grating, is a meterstick. The eye, placed close to the grating, sees virtual images of the slit along the meter sticks. Determine the wavelength of the light if each first-order image is 33.0cm from the slit. Note that the...

10 May 2018 NAME: 5) 24 points. You are given a transmission grating (diffraction grating) with 5000 lines per centimeter and asked to find the separation distance between red and blue colors pro this grating. The transmission grating is to be illuminated with red light (-632.8 nm) and blue light (?-420.0 nm) at normal incidence. The point source of white light emits uniformly in all directions. The slit is illuminated by a point source of white light that is collimated...
