Final answer:
Wavelength determines color and is measured in nanometers, with shorter wavelengths corresponding to higher frequencies and colors like violet, and longer wavelengths corresponding to lower frequencies and colors like red. Infrared radiation has lower frequencies than red light, while ultraviolet radiation, X-rays, and gamma rays have shorter wavelengths than violet light.
Step-by-step explanation:
Wavelength determines color and is measured in nanometers (nm). When discussing the properties of light, knowing the wavelength is crucial as it directly correlates to the perceived hue of the color.
Part A
Violet light has a shorter wavelength and higher frequency compared to red light. For example, red light has a wavelength of approximately 700 nm, while violet light has a wavelength closer to 380 nm.
Part B
A type of radiation that has lower frequencies than red light is infrared radiation, which typically has wavelengths longer than 720 nm.
Part C
A type of radiation that has shorter wavelengths than violet light includes ultraviolet radiation, X-rays, and gamma rays, all of which have wavelengths shorter than 380 nm.
