Answer:
Ultraviolet radiation
Step-by-step explanation:
The type of electromagnetic radiation most likely to cause skin cancer as a result of sun exposure overtime is the ultraviolet radiation.
Electromagnetic radiation occurs with a broad spectrum starting from gamma rays to the radio waves.
From one end to the other, their energy decreases as the wavelength increases.
Within this broad spectrum, the ultraviolet rays which are before the visible rays are very energetic and can cause skin cancer.
