Final answer:
Violet light has a greater frequency than red light, which has the longest wavelengths and lowest frequencies within the visible spectrum. Infrared radiation has lower frequencies than red light, and ultraviolet radiation has shorter wavelengths than violet light.
Step-by-step explanation:
When comparing the frequency of red light to violet light, it's essential to understand that red light has the longest wavelengths and lowest frequencies within the visible spectrum. On the other hand, violet light, which is on the opposite end of the spectrum, has shorter wavelengths and higher frequencies. This is because the frequency and wavelength of light are inversely related as per the wave equation c = λf, where c is the speed of light, λ (lambda) represents the wavelength, and f is the frequency.
Therefore, violet light has a greater frequency than red light. As for the parts of the spectrum, infrared radiation has lower frequencies than red light, and ultraviolet radiation has shorter wavelengths than violet light.
