The correct order for the wavelengths of different waves is Used for AM radio > Used for FM radio > Microwaves > Infrared > Visible light. This corresponds to option B.
Electromagnetic waves are ordered by their wavelength (or equivalently, frequency). Longer wavelengths correspond to lower frequencies, and shorter wavelengths correspond to higher frequencies. The order of these waves from longest wavelength to shortest is: Radio waves (including AM and FM) > Microwaves > Infrared radiation > Visible light > Ultraviolet radiation > X-rays > Gamma rays. Within the radio wave spectrum, AM radio waves typically have longer wavelengths and lower frequencies than FM radio waves.
The approximate wavelength ranges are:
– AM Radio: Hundreds to thousands of meters
– FM Radio: A few meters
– Microwaves: Centimeters to decimeters (e.g., 1 cm to 1 meter)
– Infrared: Micrometers to millimeters (e.g., 700 nm to 1 mm)
– Visible Light: Nanometers (e.g., 400 nm – 700 nm)
Based on these ranges, the correct order from longest to shortest wavelength is AM Radio > FM Radio > Microwaves > Infrared > Visible Light.
