Multiple choice

What is the relationship between the pulsation period of a star and its temperature?

  1. Pulsation period is proportional to temperature

  2. Pulsation period is inversely proportional to temperature

  3. Pulsation period is independent of temperature

  4. Pulsation period is proportional to the square of temperature
