Based on what you learned about light, select all of the correct statements from the following list. High frequency photons carry more energy than long wavelength photons. All electromagnetic waves travel at the speed of light. Light can act both as a wave and a particle. A photon is a particle of light. X-rays and gamma rays are long wavelength photons. Different types of electromagnetic radiation are fundamentally different types of waves. The only type of electromagnetic radiation that is...
