Question

Which of the following are electromagnetic waves with wavelengths between about one-thousandth of a meter and about 700-billionths of a meter?

Multiple choice question.

microwaves


infrared waves


visible light waves


radio waves

Answer 1

The electromagnetic waves with wavelengths between about one-thousandth of a meter (1 mm) and about 700-billionths of a meter (700 nm) include:

- **Microwaves** (wavelengths from around 1 mm to 1 m)
- **Infrared waves** (wavelengths from about 700 nm to 1 mm)
- **Visible light waves** (wavelengths from about 400 nm to 700 nm)

**Radio waves** typically have longer wavelengths, starting from around 1 mm and extending to kilometers, so they are not included in this specific range.

So the correct answers are:
- Microwaves
- Infrared waves
- Visible light waves
