Question

Compare the relative wavelengths of different forms of em waves?

1) Radio waves have the longest wavelength
2) Microwaves have shorter wavelength than radio waves
3) Infrared waves have shorter wavelength than microwaves
4) Visible light waves have shorter wavelength than infrared waves
5) Ultraviolet waves have shorter wavelength than visible light waves
6) X-rays have shorter wavelength than ultraviolet waves
7) Gamma rays have the shortest wavelength

Answer 1

The electromagnetic spectrum includes a range of frequencies and wavelengths from radio waves, with the longest wavelengths, to gamma rays, which have the shortest wavelengths, revealing an inverse relationship between wavelength and frequency.

Step-by-step explanation:

Electromagnetic spectrum refers to the full range of different frequencies of electromagnetic radiation (EMR), from radio waves to gamma rays. Emphasizing on their wavelengths:

1. Radio waves indeed have the longest wavelengths in the electromagnetic spectrum.
2. Moving up in energy, microwaves have shorter wavelengths than radio waves.
3. Infrared waves have even shorter wavelengths than microwaves.
4. The spectrum then proceeds to visible light, which has shorter wavelengths than infrared light.
5. Next are ultraviolet waves, which have shorter wavelengths than visible light waves.
6. Scaling further, X-rays possess shorter wavelengths than ultraviolet waves.
7. Last, gamma rays have the shortest wavelengths of all electromagnetic waves.

Since wavelength and frequency are inversely related, as the wavelength decreases from radio to gamma rays, the frequency increases.
