The shorter the wave length, the more energy. The longer the wave length, the less energy. UV is the most powerful sunlight. Can destroy DNA. IR is the weakest sunlight.
Sources:
The greater the
energy, the larger the frequency and the
shorter (smaller) the
wavelength. Given the relationship between
wavelength and frequency — the higher the frequency, the
shorter the
wavelength — it follows that
short wavelengths are more energetic than
long wavelengths.

The ozone layer, our Earth’s sunscreen, absorbs about 98 percent of this devastating UV light.
https://www.nationalgeographic.org/encyclopedia/ozone-layer/
The total mass of ozone in the atmosphere is about 3 billion metric tons. That may seem like a lot, but it is only 0.00006 percent of the atmosphere. The peak concentration of ozone occurs at an altitude of roughly 32 kilometers (20 miles) above the surface of the Earth. At that altitude, ozone concentration can be as high as 15 parts per million (0.0015 percent).

Nope. Visible light is short wave length light. IR is long wave length light.
