Radio waves possess the lowest frequency within the electromagnetic spectrum.

Understanding the Electromagnetic Spectrum

The electromagnetic spectrum encompasses a broad range of electromagnetic radiation, categorized by frequency and wavelength. These categories, arranged in order of increasing frequency (and decreasing wavelength), are:

• Radio waves: These have the longest wavelengths and lowest frequencies. They're used extensively in communication technologies, from radio broadcasting to Wi-Fi.

• Microwaves: Shorter wavelengths and higher frequencies than radio waves. Commonly used in microwave ovens and radar systems.

• Infrared radiation: Further increases in frequency and a decrease in wavelength. We experience this as heat.

• Visible light: The only part of the electromagnetic spectrum visible to the human eye. It consists of the colors of the rainbow, from red (lowest frequency) to violet (highest frequency).

• Ultraviolet radiation: Higher frequency than visible light; can cause sunburn.

• X-rays: Even higher frequency and shorter wavelengths, used in medical imaging.

• Gamma rays: The highest frequency and shortest wavelengths. These are highly energetic and potentially dangerous.

Frequency and Wavelength: An Inverse Relationship

It's crucial to understand the inverse relationship between frequency and wavelength. Wavelength refers to the distance between successive crests (or troughs) of a wave. Frequency represents the number of complete wave cycles passing a given point per unit of time (typically measured in Hertz, Hz). As frequency increases, wavelength decreases, and vice versa. This relationship is constant for all electromagnetic radiation.

In Conclusion

Therefore, among all types of electromagnetic waves, radio waves unequivocally exhibit the lowest frequency. Their longer wavelengths are a direct consequence of their lower frequency.
