#8 Which electromagnetic wave has the most energy? Explain why.

• Gamma rays, because their waves have a low frequencies

• Radio, because their waves have low frequencies

• Radio, because their waves have high frequencies

• Gamma rays, because their waves have a high frequencies and short wavelengths

• Ultraviolet, because their waves can cause sun burns.
