If a wave has a wavelength of 467 nm, what type electromagnetic radiation was measured?
infrared radiation
red on the visible light spectrum
ultraviolet radiation
indigo on the visible light spectrum
A?
To determine the type of electromagnetic radiation, we can refer to the electromagnetic spectrum. The electromagnetic spectrum consists of different types of radiation, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
The wavelength mentioned is 467 nm (nanometers).
Visible light ranges from approximately 400 nm to 700 nm.
Since the wavelength of 467 nm falls within this range, it indicates that the measured radiation is part of the visible light spectrum.
To be more specific, the color corresponding to 467 nm is on the blueish side. The sequence of colors in the visible light spectrum, in increasing order of wavelength, is: violet, indigo, blue, green, yellow, orange, and red.
Therefore, a wavelength of 467 nm would correspond to the color "indigo" on the visible light spectrum. Hence, the correct answer is "indigo on the visible light spectrum."
