Skin
If it is a human then the skin protects the entering of strong ultraviolet rays. In animals its the same. In plants the other covering of the cuticle protects to plant from being exposed to these rays.
The human retina is not very sensitive to ultraviolet (UV) light. The lens of the eye absorbs much of the UV radiation before it reaches the retina, protecting it from potential damage. However, prolonged exposure to intense UV light can still cause harm to the eyes.
Ultraviolet light has a wavelength below 400 nanometers, infrared;s wavelength is less than 700 nanometers or so. Frequency is inversely proportional to wavelength, so ultraviolet light has a much a much higher frequency than infrared.
A schefflera plant thrives in bright, indirect light. It should not be exposed to direct sunlight for long periods as it can cause the leaves to burn.
Ultraviolet light has higher energy than visible light but lower energy than X-rays. The energy of ultraviolet light ranges from about 3 eV to 124 eV, depending on the specific wavelength.
It blocks much of the ultraviolet light from the sun.
The ultraviolet light of the sun will give you good color, but too much exposure can be dangerous.

No. The reason is that ultraviolet light are relevant to the sunlight where as we know that no bacteria can stand too much heat, hence bacteria can't persist in (U.V - radiations)...
The wavelengths for UV light are shorter than for visible light, but much longer than for x-rays or gamma rays.
When someone talks about exposure in photography, they're talking about the level of light in an image. A photograph can be overexposed (too much light), underexposed (not enough light) or well exposed (the light is just right).
There are an infinite number of wavelengths above visible, below visible, and within visible. Since reality has infinite resolution, we can imagine varying the wavelength with infinite division. To call out bands of wavelength: Ultraviolet, X-rays, & Gamma rays.
