• A. Wavelength, frequency, and amplitude
• B. Color, taste, and odor
• C. Density, pressure, and volume
• D. Mass, charge, and temperature

Answer: (A)

Verified step by step guidance

1. Understand that electromagnetic energy can be described by its physical properties related to waves.
2. Recall that electromagnetic waves have characteristics such as wavelength, frequency, and amplitude, which define their behavior and energy.
3. Wavelength (\(\lambda\)) is the distance between successive peaks of the wave and determines the type of electromagnetic radiation.
4. Frequency (\(\nu\)) is the number of wave cycles that pass a point per second and is inversely related to wavelength by the equation \(\nu = \frac{c}{\lambda}\), where \(c\) is the speed of light.
5. Amplitude relates to the wave's intensity or brightness and corresponds to the energy carried by the wave.
