Answer:

Ultraviolet Light or UV

Step-by-step explanation:

Ultraviolet Light is beyond the violet in the spectrum, corresponding to light having wavelengths shorter than 4000 angstrom units.

Wavelength are the distance, measured in the direction of propagation of a wave, between two successive points in that the wave that are characterized by the same phase of oscillation.

Ultraviolet (UV) light is a form of radiation that acts as a mutagen, an agent that causes mutations in DNA.

All molecules are made of atoms that are bound together by electric charge. An energetic UV photon can strike an atom in the DNA, transfer some of its energy to the atom and raise that atom’s energy level such that electrons move outward or even leave the atom this breaks the bound in the molecule.

There is nothing magic about UV radiation. Any kind is is energetic radiation can do this but UV is just really common so you are exposed to so much of it.

Fortunately our cells have a way to repair damaged DNA but the repair is not always perfect and if this happens enough times the cell is damaged because the DNA is damaged. If you are VERY unlucky a cell is damaged in just the right way (or “just the wrong way”) so that it can still live but its ability to regulate growth is damaged. We call this “cancer” Skin cancers is actually a “one in a trillion” freak accident but you have billions of cells and that are exposed to trillions of UV photons and after some long number of years that “one in a trillion” freak accident actually happens and a cell is damages in just the wrong place and you immune system some how does not notice and leave it alone.
