Anuclear explosion may release tremendous amounts of energy in the form of noise, heat, visible light, radiation and an atmospheric shock wave. an observer watching the explosion from the vacuum of nearby space would be able to experience which of these types of energy? a) heat and radiation b) sound and radiation c) light and radiation d) heat, light, and the shock wave

light and radiation is able to experience by an observer watching the explosion from the vacuum.

Explanation:

Basically in the nuclear explosion, there will be an enormous of energy released as noise, heat, visible light, radiation and atmospheric wave. Usually sound and wave propagate through medium but in vacuum, there will be no medium to transfer this type of energy. so there is no chance of sound and wave transfer.  Light and radiation travel in vacuum because they didn't need the medium to transfer .  

Independent variable is something that is changed in a experiment.
