You observe a star very similar to our own Sun in size and mass. This star moves very slightly back and forth in the sky once every 4 months, and you attribute this motion to the effect of an orbiting planet.
 
  What can you conclude about the orbiting planet?
  A) The planet must be closer to the star than Earth is to the Sun.
  B) The planet must be farther from the star than Neptune is from the Sun.
  C) The planet must have a mass about the same as the mass of Jupiter.
  D) You do not have enough information to say anything at all about the planet.

Question 2

How are wavelength, frequency, and energy related for photons of light?
 
  A) Longer wavelength means higher frequency and lower energy.
  B) Longer wavelength means lower frequency and lower energy.
  C) Longer wavelength means lower frequency and higher energy.
  D) Longer wavelength means higher frequency and higher energy.
  E) There is no simple relationship because different photons travel at different speeds.
