Week 9 Homework Assignment
- If 480-nm and 620-nm light passes through two slits 0.54mm apart, how far
apart are the second order fringes for these two wavelength on a screen 1.6m
away?
- A light beam strikes a piece of glass at a 60.00° incident angle. The beam
contains two wavelengths, 450.0nm and 700.0nm, for which the index of
refraction of the glass is 1.4820 and 1.4742, respectively. what is the angle
between the two refracted beams?
- If a slit diffracts 550-nm light so that the diffraction maximum is 3.0cm
wide on a screen 1.50m away, what will be the width of the diffraction maximum
for light with a wavelength of 400nm?
- The first-order line of 589-nm light falling on a diffraction grating is
observed at a 15.5° angle. How far apart are the slits? At what angle will
the third order be observed?
- White light containing wavelengths from 400nm to 750nm falls on a grating
with 7500lines/cm. How wide is the first-order spectrum on a screen 2.30m
away?
