In this report i will be discussing ultra-violet and infra-red radiation, i will discuss the properties and generation of each, the effects and uses and the harmful effects of each. This will give me a better understanding of these.

Properties and generation of ultra violet radiation
All of the waves in the electromagnetic spectrum have the same speed but they have different frequencies or wavelengths. Frequency and wavelength of a wave are used in physics to describe the characteristics of the wave. The wavelength is a measure of how spread out the wave is and is measured in metres, in the electromagnetic spectrum the waves are so small that we talk about nanometres. The frequency (f) of a wave is the number of waves that pass a point in 1 second; the units of frequency are hertz (Hz).
Ultraviolet has a smaller wavelength than visible light, thus meaning it has a higher frequency and higher in energy than visible light, the waves can be found beyond the violet end of the visible region of the electromagnetic spectrum. The shorter the wavelength, the higher the energy and the higher the possible damage could be. It is invisible to the naked eye, only forms 3% of light from the sun it is one of the most damaging.
There are 3 types of ultraviolet radiation​
UVA which has a longest wavelength of 315 – 400 nanometres
It is necessary for healthy growth and helps to produce vitamin D. Also...
