Properties of Ultraviolet Waves

➡️Wavelength(m)-1 x 10-8 - 4 x 10-7

➡️Frequency (Hz)-7.5 x 1014 - 3 x 1016

➡️HAve shorter wavelengths than visible light

➡️The are invisible to the human eye but can be seen by some insects and animals; bumblebees, birds, reptiles

➡️The Ultraviolet part of the Em spectrum has been divided into three regions: Near ultraviolet, Far Ultraviolet, Extreme ultraviolet

➡️The three regions are distinguished by how energetic the ultraviolet radiation is, and by the Wavelength of the ultraviolet light which is related to energy

➡️The Near Ultraviolet, abbreviated (NUV), is the light closest to optical or visible light

➡️The far ultraviolet, abbreviated FUV, lies between the near and extreme ultraviolet regions. It is the least explored of the three regions.

➡️The extreme ultraviolet, abbreviated (EUV), is the ultraviolet light closest to X-rays, and is the most energetic of the three types.

➡️Banks use UV light to check for counterfeit money .

➡️Uv light can be blocked by thick clouds.
