(i) A sodium light of wavelength 580 nm falls on two narrow slits. The distance
between the third dark fringe to the central bright on a screen is 3.5 mm. Distance
between slits and screen is 160 cm. What is the spacing between the two slits?
(ii) Solar cells are an example of anti-reflective coatings. Let a silicon solar cell (n
= 3.45) coated with a layer of silicon dioxide (n = 1.45). Calculate the minimum
coating thickness that will minimize the reflection of the light with wavelength
of 650 nm?
*59. (III) One of the beams of an interferometer (Fig. 24–61)
passes through a small evacuated glass container 1.155 cm
deep. When a gas is allowed to slowly fill the container,
a total of 158 dark fringes are counted to move past a
reference line. The light used has a wavelength of 632.8 nm.
Calculate the index of refraction of the gas at its final
density, assuming that the interferometer is in vacuum.

- In a thermally stabilized lab, a Michelson interferometer is used to monitor the temperature to ensure it stays constant. The movable mirror is mounted on the end of a 1.00-m-long aluminum rod, held fixed at the other end. The light source is a He Ne laser, =632.8 nm .
