Jaclynn Hilligoss ASTR 100 Section 0203 Homework #4 1. Types of Light lowest to highest energy:  Radio, Infrared, Visible, Ultraviolet, X-Rays,  Gamma Rays Lowest to highest frequency:  Radio, Infrared, Visible, Ultraviolet, X-Rays, Gamma Rays  *Same because frequency easily relates to the amount of energy it has- frequency is the  amount of times a wave oscillates  Shortest to longest wavelength:  Gamma Rays, X-rays, Ultraviolet, Visible, Infrared, Radio *Opposite because frequency is measured in how many times a wave oscillates it only  makes sense that longer waves will have a lower frequency and lower energy where as  shorter wave will move quicker and at a faster rate. 2. (a) Earth’s light wavelength= 1.0 x 10^-6 m = 1000 nm What type of light is this? Infrared (b) Frequency? Energy of light wave? (c) Speed of light wave? 3. Frost Line? Temp diff in the solar nebula? Frost line is the boundary between the Jovian planets and the terrestrial planets in  relationship to the molecules (materials) that could be formed. On the far side of the line  it’s cool enough for compounds like water, ammonia, and methane to condense into solid  ice grains- Whereas this doesn’t happen on the opposite side closer to the protosun. The  planets were formed in the spinning disk around the sun, when the temp was low enough
