Ultraviolet+Waves

=Unit 2 Optics=

Chapter 4 Many properties of light can be understood using a wave model of light.
4.3 Light and Electromagnetic Spectrum

Ultaviolet Waves are a type of electromagnetic radiation that, relative to light, has a shorter wavelength and higher energy and frequency.Your body makes vitamin D which you need for healthy bones and teeth when the ultraviolet radiation strikes your skin. But an overexposre to ultraviolet radiation can result sunburns and skin cancers, and also damage to the surface of the eye.
