Do radio waves have a longer or shorter wavelength compared to visible light?

Radio waves have a longer wavelength compared to visible light. The electromagnetic spectrum includes a range of electromagnetic radiation types, each characterized by its wavelength and frequency. Radio waves exist at the low-frequency end of the spectrum, with wavelengths that can be a few millimeters to several kilometers in length. In contrast, visible light occupies a much smaller portion of the spectrum, with wavelengths ranging from about 400 to 700 nanometers. This difference in wavelength is fundamental to understanding how various types of electromagnetic radiation are used and their interactions with matter.

Thus, the distinction between radio waves and visible light in terms of wavelength is clear, with radio waves being significantly longer, which also contributes to the different applications and behaviors of these types of waves in various technologies and scientific fields.
