The question "Which of the following has the longest wavelength?" requires a list of options to compare. Wavelength is inversely proportional to frequency; lower frequency means a longer wavelength. Therefore, to answer definitively, we need the specific options provided.

However, we can discuss the general principles governing wavelength across the electromagnetic spectrum:

Understanding Wavelength

Wavelength is the distance between two consecutive crests (or troughs) of a wave. It's typically represented by the Greek letter lambda (λ) and measured in units such as meters, nanometers, or angstroms. Different types of electromagnetic radiation have vastly different wavelengths.

The Electromagnetic Spectrum

The electromagnetic spectrum encompasses a broad range of wavelengths, from extremely short gamma rays to very long radio waves. The order from shortest to longest wavelength is:

• Gamma rays: These have the shortest wavelengths and highest frequencies.
• X-rays: Shorter wavelengths than ultraviolet light.
• Ultraviolet (UV) light: Shorter wavelengths than visible light.
• Visible light: The only part of the electromagnetic spectrum we can see, with wavelengths ranging from violet (shortest) to red (longest).
• Infrared (IR) light: Longer wavelengths than visible red light.
• Microwaves: Longer wavelengths than infrared light.
• Radio waves: These have the longest wavelengths and lowest frequencies. Within radio waves, there's a further division into various bands (e.g., AM, FM, etc.), each with specific wavelength ranges.

Determining the Longest Wavelength from a List

To identify which option from a given list has the longest wavelength, compare the options based on their position within the electromagnetic spectrum. The option representing the type of radiation closest to radio waves will have the longest wavelength. For example:

Example List: Visible light, X-rays, microwaves, infrared radiation

Answer: Radio waves would have the longest wavelength from this list. However, microwaves would have the longest wavelength among the provided options.

In conclusion, without a specific list of options, it's impossible to definitively answer the question. Remember to always consider the electromagnetic spectrum when comparing wavelengths of different types of electromagnetic radiation.
