Electromagnetic radiation emitted by a planet has a wavelength of 10 micrometers (1 µm = 10-⁶ m).What name is given to this type of electromagnetic radiation?
A) gamma rays
B) infrared radiation
C) radio waves
D) visible light

Question

Quizplus · Accepted Answer

The wavelength of 10 micrometers falls in the range of infrared radiation, which has wavelengths longer than those of visible light but shorter than radio waves. Therefore, the correct choice is B, infrared radiation. A, gamma rays, are shorter wavelengths than X-rays, while C, radio waves, have longer wavelengths than microwaves. D, visible light, has wavelengths between approximately 400 and 700 nanometers, which is much shorter than 10 micrometers.
