Every different wavelength of e-m ratiation has a certain amount of energy associated with it. Visible light is a very small part of the e-m spectrum and does not have enough energy to cause severe damage. UV has more energy which makes it capable of interacting with the molecules in the body, causing damage.
Ultraviolet Radiation, with prolonged contact with the skin, can later in life cauuse skin cancer
higher frequency... resonance with DNA
Melanin is a substance produced by the skin that protects the skin from ultraviolet radiation. It also gives skin its color.
Ultraviolet radiation can be a cause of skin cancers.
UV radiation is harmful to skin. It causes skin cancer.
SKIN CANCER!
Protection from ultraviolet radiation is what we use sunblock for. UV (ultraviolet) rays have high energy and can damage skin.
No; ultraviolet radiation stimulates the skin to produce melanin. UV light also converts a precursor to vitamin D in the skin.

Ultraviolet is ionising radiation. That means that it will ionise (turn into ions) some substances due to being a high energy form of electromagnetic radiation. If these 'substances' happen to be in your skin then you can start to see how UV radiation can be bad.

No, melanin protects the skin from ultraviolet radiation. Vitamin D is synthesized in the skin and help with calcium absorption.
