Ultraviolet radiation from the sun has a higher frequency than radar waves.

Here's why:

* Electromagnetic Spectrum: Both ultraviolet radiation and radar waves are part of the electromagnetic spectrum. This spectrum arranges electromagnetic radiation by its frequency (and wavelength).

* Frequency and Energy: Higher frequency electromagnetic radiation carries more energy.

* Ultraviolet vs. Radar: Ultraviolet radiation has a much higher frequency than radar waves. This means ultraviolet radiation is more energetic.

In short: The order of increasing frequency (and therefore energy) is:

1. Radar Waves (low frequency)

2. Ultraviolet Radiation (high frequency)
