UV-A
The UV rays are of three types. they are UV-A, UV-B, UV-C.
The ozone layer primarily absorbs ultraviolet (UV) radiation from the sun, particularly UV-B and UV-C rays. This absorption helps to protect Earth's surface from the harmful effects of these high-energy radiations.
UV is commonly broken up into three rough groupings called UV-A, UV-B, and UV-C. Oxygen and nitrogen absorb UV-C and break apart. Some of the oxygen forms ozone. Ozone absorbs UV-C and some UV-B and breaks apart. Ozone also absorbs UV-B and reradiates it randomly. UV-A (the sutff good for tanning) is pretty much just passed thru to the surface of the Earth. So some UV is blocked by oxygen (UV-C), just not any of UV-B, which directly strikes our DNA since we are largely transparent to UV-B and DNA is not.
The ozone layer in the Earth's stratosphere is responsible for absorbing most of the ultraviolet (UV) radiation from the sun. Specifically, the ozone molecules absorb UV-B and UV-C radiation, protecting living organisms from the harmful effects of excessive UV exposure.
No, ultraviolet A (UVA) radiation is not the lowest on the electromagnetic spectrum. It falls between ultraviolet B (UVB) and visible light in terms of wavelength and energy. UVA radiation is longer in wavelength compared to UVB, but shorter than visible light.
On the violin the G string, which is the G under middle C, has the lowest frequency (196Hz).
The UV rays are of three types. they are UV-A, UV-B, UV-C.
UV-B and UV-C are filtered by the ozone layer present in the atmosphere and only UV-A reaches to the earth which cause the various skin infection. if we talk about the frequency of the UV-B and UV-C the because of the higher frequency the UV-C is more harmful. UV with the wavelength of 253.7 nm is used for its germicidal activity.

UV light has a frequency range of approximately 7.5 x 10^14 Hz to 3 x 10^16 Hz. The corresponding wavelength range is about 10 nm to 400 nm, depending on the specific type of UV light (UV-A, UV-B, or UV-C). UV light is invisible to the human eye but has important applications in various fields such as sterilization, fluorescence, and phototherapy.

U.V can be separated according to its energy level and wavelength with UVa having the lowest energy and longest wavelength followed by UVb and ultimately UVc which has the shortest wavelength and highest energy level. You may be familiar with UVa and UVb as the part of the suns rays which cause tanning, aging, and skin cancer. The Sun also emits UVc the most powerful and dangerous type of U.V., fortunately for us most of this is stopped in the upper atmosphere by gasses like ozone.

Ultraviolet (UV) radiation, specifically in the UV-B and UV-C ranges, can cause damage to the eyes, leading to conditions such as photokeratitis and cataracts. It is important to protect the eyes from UV exposure by wearing sunglasses that block both UV-A and UV-B rays.
The notes in the C major scale from highest to lowest are C, D, E, F, G, A, and B.
In a string orchestra, the instrument with the lowest pitch is the Bass (also called Double Bass, String Bass, Upright Bass, and Contrabass)
