Desert mirages are inverted images. From this, what can we conclude about the index of refraction of hot air compared to cold air?

  1. nHOT AIR > nCOLD AIR
  2. nHOT AIR + nCOLD AIR
  3. nHOT AIR < nCOLD AIR
  4. Mirages have nothing to do with refraction

The sun appears to be yellow when overhead because:

  1. The human eye is most sensitive to yellow
  2. Yellow frequencies are transmitted better through the atmosphere
  3. Air does not absorb yellow frequencies
  4. The temperature of the Sun is 6000K
  5. None of the above

The sky appears to be blue during the day because:

  1. Air absorbs blue light less than any other frequency
  2. Air molecules emit blue light after being struck by sunlight
  3. The sky reflects blue light from the oceans
  4. The temperature high in the Earth’s upper atmosphere is 1000K
  5. None of the above

  2. They are both traveling in the same direction
  3. They are traveling in opposite directions
  4. They are both from the same source

A particular object appears to be red. The reason it appears red is.

  1. It absorbs ONLY RED frequencies as they hit it
  2. It reflects ONLY RED frequencies as they hit it
  3. It absorbs RED frequencies MORE than any other frequencies
  4. It reflects RED frequencies MORE than any other frequencies
  5. It emits RED frequencies more than any other frequencies
  6. Not enough information

The phenomenon of interference arises due to:

  1. Superposition of waves
  2. Coherence of wave trans
  3. Sensitivity of the light
  4. Cancellation between the two waves
  5. Inability of the medium to respond to the wave disturbance
  6. Something else

A rainbow appears on an oil slick or soap bubble due to:

  1. Refraction of light
  2. Transmission of light
  3. Dispersion of light
  4. Interference of light
  5. Scattering of light
  6. Something else

no charges within the regions shown, which represent(s) a possible
electric field?

  1. 1 only
  2. 4 only
  3. 1 and 3
  4. 2 and 4
  5. 3 and 4
  6. None of the above

  2. Real, inverted, and smaller than the object
  3. Real, inverted, and larger than the object
  4. Virtual, upright, and smaller than the object
  5. Virtual, inverted, and larger than the object
  6. Virtual, upright, and larger than the object
  7. None of the above
