Which type of electromagnetic wave has the shortest wavelength?Select one:a. X-raysb. Radio wavesc. Microwavesd. Infrared waves

Step 1: Break Down the Problem

We need to identify which type of electromagnetic wave from the given options has the shortest wavelength.

Step 2: Relevant Concepts

The electromagnetic spectrum is divided into various regions based on wavelength. The regions from shortest to longest wavelength are as follows:

1. Gamma rays
2. X-rays
3. Ultraviolet light
4. Visible light
5. Infrared waves
6. Microwaves
7. Radio waves

Step 3: Analysis and Detail

From the list above, we can see that X-rays have a shorter wavelength compared to the other options provided (radio waves, microwaves, and infrared waves).

Step 4: Verify and Summarize

To conclude, X-rays are known to have wavelengths ranging from approximately 0.01 to 10 nanometers, which are significantly shorter than the wavelengths of radio waves (which can be from about 1 millimeter to 100 kilometers), microwaves (1 millimeter to 1 meter), and infrared waves (700 nanometers to 1 millimeter).

Final Answer

The type of electromagnetic wave with the shortest wavelength is a. X-rays.
