Homework Help: Venus the hottest planet

  1. Apr 29, 2008 #1
    The dense atmosphere on the planet Venus makes Venus the hottest planet in the solar system, even hotter than Mercury the closest planet to the Sun. suggest an explanation for this anomaly that involves the electromagnetic spectrum.

    - Electromagnetic waves travel slower in denser mediums, and also there will be more refraction and chances of total internal reflection increases the EM waves within the atmosphere at one time.

    What does the peak wavelenght of a black body depend on?
    Think of the peak wavelengths emitted by a star and a planet.
    What wavelengths get absorbed by an atmosphere?

    It may also be an idea to consider how Venus' atmosphere differs to Earth (by compound).

    I was pretty sure it had to do with the greenhouse effect.
