energy from fusion in the sun becomes electromagnetic radiation. travels to earth in a process called radiation.
wavelength: long —————————————————————————————————————————————————————————→ short
frequency: low —————————————————————————————————————————————————————————→ high
energy: low —————————————————————————————————————————————————————————→ high
________________________________ ___________ ___________ __ __
___________ _____ ______

Explanation:

For the Nuclear Fission and Fusion blanks:

• Fission: A large atom splits (undergoes nuclear fission) into two smaller atoms, releasing a lot of energy (and often neutrons, but energy is the key here for the blank).
• Fusion: Two small atoms combine (undergo nuclear fusion) to form a larger atom, also releasing a lot of energy (fusion in stars like the Sun releases massive energy).

For the Sun's energy: Fusion in the Sun produces electromagnetic radiation (light, heat, etc. are electromagnetic waves). This travels to Earth via radiation (the process of energy transfer through electromagnetic waves, as conduction/convection don’t work in space).

For the wavelength - frequency - energy relationships (electromagnetic spectrum):

• Long wavelength → Low frequency → Low energy (e.g., radio waves).
• As wavelength shortens, frequency increases, and energy increases (e.g., microwaves → infrared → visible → ultraviolet → X - rays → gamma rays, with gamma rays having the shortest wavelength, highest frequency, and highest energy). So the blanks under wavelength, frequency, energy would be filled with types of electromagnetic radiation: e.g., Radio Waves (long, low, low), Microwaves, Infrared, Visible Light, Ultraviolet, X - Rays, Gamma Rays (short, high, high). But the main blanks for fission/fusion and Sun energy are about the processes and energy release.

Answer:

• Fission: one large atom splits to become two smaller atoms plus lots of energy
• Fusion: two small atoms combine to become one bigger atom plus lots of energy
• Energy from fusion in the Sun becomes electromagnetic radiation. Travels to Earth in a process called radiation
• For wavelength - frequency - energy (electromagnetic spectrum example fill - ins, from left (long/low/low) to right (short/high/high)): Radio Waves, Microwaves, Infrared, Visible Light, Ultraviolet, X - Rays, Gamma Rays (with Radio Waves on the far left for long wavelength, low frequency, low energy; Gamma Rays on the far right for short wavelength, high frequency, high energy)
