Answer:
A1. Radio waves have the longest wavelength, while gamma rays have the shortest wavelength.
A2. Radio waves have the lowest frequency, while gamma rays have the highest frequency.
A3. Radio waves carry the lowest photon energy, while gamma rays carry the highest photon energy.
A4. Radio waves and gamma rays lie at the ends of the visible light spectrum.
A5. Red has the longest wavelength in the visible spectrum, while violet has the shortest wavelength.
A6. Red has the lowest frequency in the visible spectrum, while violet has the highest frequency.
A7. Red carries the lowest photon energy in the visible spectrum, while violet carries the highest photon energy.
A8. The higher the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength.
A9. The shorter the wavelength, the higher the energy. The longer the wavelength, the lower the energy.
A10. The higher the frequency, the higher the energy. The lower the frequency, the lower the energy.
