Final answer:
Visible light consists of waves that are part of the electromagnetic spectrum, with two main physical qualities: wavelength and amplitude.
Step-by-step explanation:
Visible light consists of waves that are part of the electromagnetic spectrum. The two main physical qualities of energy in the electromagnetic spectrum are wavelength and amplitude. Wavelength determines the color of light, with shorter wavelengths corresponding to colors like blue and longer wavelengths corresponding to colors like red. Amplitude, on the other hand, determines the brightness or intensity of light.
