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...

The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a. What is the resolving power of the grating? b. What is the slit...

(1) Derive the equation that relates the wavelength λ to the
distance Ym=1 of the m=1 line.
You must provide the justification for your derivation.
(2) Describe, step by step, how the experimental data has to be
analysed to determine the
unknown wavelength λ3. You must be brief but clear in your
description of the method.
