A silicon monoxide (n = 1.45) film of 330 nm thickness is used to coat a glass camera lens (n = 1.56). What wavelength of light in the visible region (390 to 710 nm) will be most efficiently transmitted by this system? (1 nm = 10-9 m)
 a. 522 nm
  c. 638 nm
  b. 492 nm
  d. 409 nm

Question 2

Consider two containers with the same volume and temperature. Container One holds dry air (a mixture of nitrogen and oxygen). Container Two holds moist air. The moist air has the same ratio of nitrogen to oxygen molecules but also contains water vapor. According to the ideal gas law, if the pressures are equal, the weight of the gas in Container One will be:
 a. lighter than the gas inside the second container.
  b. equal to the weight of the gas in the second container.
  c. heavier than the gas inside the second container.
  d. all the above are incorrect because the pressures cannot be equal.
