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


radio waves


visible light waves


infrared 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** (typically from about 1 mm to 30 cm)
- **Infrared waves** (typically from about 700 nm to 1 mm)
- **Visible light waves** (from about 400 nm to 700 nm)

**Radio waves** are generally longer than 1 mm.

So the correct answers are:

- **Microwaves**
- **Infrared waves**
- **Visible light waves**
