Final answer:
The wavelength of radio waves is more than 1 x 10^-1 meters. They range approximately from 1 meter to hundreds of meters long, making them the electromagnetic radiation with the longest wavelengths.
Step-by-step explanation:
The wavelength of radio waves is more than 1 x 10-1 meters (option b). Radio waves are a type of electromagnetic radiation and have the longest wavelengths in the electromagnetic spectrum. They can have wavelengths that range from about 1 meter to hundreds of meters (100 to 103 meters). For instance, AM radio waves fall into the kilohertz (kHz) frequency range which translates into longer wavelengths, while FM radio waves with frequencies in the megahertz (MHz) range have shorter wavelengths within the radio spectrum.
It’s important to understand that in the electromagnetic spectrum, as the frequency increases, the wavelength decreases, and vice versa. Different applications across the radio spectrum utilize various wavelengths. For example, commercial radio stations use frequencies designated for AM and FM bands, with wavelengths calculated based on their specific frequencies.
