Assignment

1. The pulse width of xenon flash lamps, such as those used in photography, is in the:

   1. Microsecond time scale
   2. Millisecond time scale
   3. Nanosecond time scale
   4. Picosecond time scale

2. A short pulse of light is used to interact with a sample that has been placed in the optical path of a spectrometer. The result of the interaction can be:

   1. Transient absorption
   2. Passive absorption
   3. Active absorption
   4. None

3. XeCl provides laser emission at 308 nm with a 0.3 nm spectral width and a pulse width of about:

   1. 19 nanoseconds
   2. 10 nanoseconds
   3. 40 nanoseconds
   4. 50 nanoseconds
