They have a longer wavelength than radio waves.

They have a higher frequency than visible light.

They have a lower frequency than infrared rays.

Answer 1

Let's evaluate the statements about microwaves based on their position in the electromagnetic spectrum:

1. **They have a shorter wavelength than ultraviolet rays.**
- This statement is **false**. Microwaves have longer wavelengths than ultraviolet rays.

2. **They have a longer wavelength than radio waves.**
- This statement is **false**. Microwaves have shorter wavelengths than most radio waves.

3. **They have a higher frequency than visible light.**
- This statement is **false**. Microwaves have a lower frequency than visible light.

4. **They have a lower frequency than infrared rays.**
- This statement is **true**. Microwaves have a lower frequency than infrared rays.

The correct statement regarding microwaves is:

**They have a lower frequency than infrared rays.**
