What is an example of a long wavelength electromagnetic wave?

• A. Infrared waves
• B. Visible light
• C. X-rays
• D. Radio waves

Answer: (D)

Radio waves are an example of long wavelength electromagnetic waves and occupy the lower frequency end of the electromagnetic spectrum. They typically have wavelengths that can range from a few millimeters to several kilometers, making them significantly longer compared to other types of electromagnetic radiation. In the context of the electromagnetic spectrum, the longer the wavelength, the lower the frequency, and radio waves illustrate this principle effectively. They are used in various applications, including communication technologies such as radio broadcasts, television, and mobile phone transmissions. Understanding the position of radio waves in the spectrum helps in recognizing their unique properties and practical uses. Infrared waves have shorter wavelengths than radio waves but are still part of the electromagnetic spectrum. Visible light, on the other hand, has an even shorter wavelength range and encompasses the light that the human eye can perceive. X-rays are among the highest energies in the electromagnetic spectrum and have much shorter wavelengths than both infrared and radio waves.
