Frequency:

- Radio waves have the lowest frequency.
- Microwaves have slightly higher frequency.
- Infrared radiation has a higher frequency than microwaves.
- Visible light has a higher frequency than infrared.
- Ultraviolet radiation has a higher frequency than visible light.
- X-rays have a higher frequency than ultraviolet radiation.
- Gamma rays have the highest frequency.

Wavelength:
- Radio waves have the longest wavelength.
- Microwaves have shorter wavelength than radio waves.
- Infrared radiation has a shorter wavelength than microwaves.
- Visible light has a shorter wavelength than infrared.
- Ultraviolet radiation has a shorter wavelength than visible light.
- X-rays have a shorter wavelength than ultraviolet radiation.
- Gamma rays have the shortest wavelength.

So what are the two answers

Frequency: Increases from left to right on the electromagnetic spectrum (from radio waves to gamma rays).

Wavelength: Decreases from left to right on the electromagnetic spectrum (from radio waves to gamma rays).
