Final answer:
The properties of visible electromagnetic waves that change with color are wavelength, frequency, and energy. These properties are interconnected and vary inversely with one another; as wavelength increases, frequency and energy decrease, and vice versa for decreasing wavelength. Therefore, the correct option is 5.
Step-by-step explanation:
For a given number of photons, the properties of visible electromagnetic waves that change with color are wavelength, frequency, and energy. The wavelength of light determines the color we perceive, and it is inversely related to frequency and energy. According to the electromagnetic spectrum, as the wavelength increases, the frequency decreases, and so does the energy of the photons. Conversely, shorter wavelengths correspond to higher frequencies and greater energies.
Therefore, when considering the color of a visible electromagnetic wave, all three properties can change. This means that the correct answer is option 5) All of these. Blue light has a shorter wavelength than red light, which means it has higher frequency and energy. Similarly, green light has more energy than red light but has a shorter wavelength.
The equations that relate these properties are c = λf (where c is the speed of light, λ is the wavelength, and f is the frequency) and E = hν (Planck's law, where E is the energy of the photon and ν is the frequency).
