Electromagnetic spectrum ( diamora purba)

# data[].attributes.body
The electromagnetic spectrum consists of both waves and particles and is categorised by wavelength

# data[].attributes.body
The electromagnetic spectrum is a diagram that show the different types of electromagnetic waves, ordered from shortest wavelength (/highest frequency/highest energy) to longest wavelength (/lowest frequency/lowest energy)

# data[].attributes.body
High frequency and short wavelength

# data[].attributes.body
Radio waves have the longest wavelength , lowest frequency and have a low energy, making them ideal for sending data for communication purposes (i.e. radio, tv), as they can also bend around objects. The two types of radio (AM and FM) stand for Amplitude Modulation and Frequency Modulation, which describes which aspect of the wave is changed (amplitude or frequency), and hence have different properties (i.e. different wavelengths) and uses (i.e.news reports = AM, music = FM)

electromagnetic radiation with longer wavelength of those in visible light

# data[].attributes.body
Ultraviolet designates a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and contributes about 10% of the total light output of the Sun. Ultraviolet (UV) designates a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and contributes about 10% of the total light output of the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.

Suntan and sunburn are familiar effects of over-exposure of the skin to UV, along with higher risk of skin cancer. Living things on dry land would be severely damaged by ultraviolet radiation from the Sun if most of it were not filtered out by the Earth's atmosphere.[1] More energetic, shorter-wavelength "extreme" UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground.[2] Ultraviolet is also responsible for the formation of bone-strengthening vitamin D in most land vertebrates, including humans (specifically, UVB).[3] The UV spectrum thus has effects both beneficial and harmful to human health.

The lower wavelength limit of human vision is conventionally taken as 400 nm, so ultraviolet rays are invisible to humans, although some people can perceive light at slightly shorter wavelengths than this (see below). Insects, birds, and some mammals can see near-UV (i.e. slightly lower wavelengths than humans can see).

The Dangers of the Em Spectrum

As the wavelength of Em spectrum changes Pam the way the different wavelengths interact with smaller matter also changes

As the frequency increases, wavelength gets smaller. Eventually the waves are so small that they can interact with cells, DNA and atoms. This is called Ionizing Radiation
