Wavelengths
Different wavelengths have different effects depending on what type of wave it is. Light rays will display more red if the wavelength is longer and if the wavelength is shorter the light will display more blue. How we interpret waves depends on what type of wave it is. It’s different for sound waves, lightwaves etc. Normally a shorter wavelength means that it is more energetic than longer ones. Wavelength is normally measured by the distance between 1 wave and another, in a repeated pattern. Frequency is very similar to this. It is the measurement of waves that have passed in between 1 second. Wavelengths have been grouped depending on their wavelength from longest wavelength to the shortest on the electromagnetic spectrum.

The Electromagnetic Spectrum
Radio - Radio waves are mainly used for communications because it has a very long wavelength and can travel long distances and still keep a strong connection.
Microwave - Certain frequencies of microwaves can be absorbed by water molecules and heat them up which means microwaves can be used for cooking and heating food. Although microwaves are also occasionally used to transmit messages.
Infrared - Infrared, like most other rays is invisible. It’s very sensitive to temperature and releases thermal radiation depending on the temperature. We display the different amounts of thermal radiation with different colours with red being hotter and blue being colder with infrared technology.
Visible Light - Visible light is the light we see all the time like sunlight, the light from your ipad or computer. The reason why you feel more awake while in front of the computer or ipad because light from devices shines in the spectrum of blue. Light that shines more blue will increase long term planning, creativity, activeness, awareness and better decision making. Light that shines more red can cause faster reaction times, quick thinking, alertness and even 200% faster healing.
Ultraviolet - UV lights are in lights and lanterns. Ultraviolet light is present in sunlight which isn't harmful on its own but it can cause chemical reactions with the skin and cause cancer and can be fatal. It is split into 3 categories, UVA, UVB and UVC.
X-Ray - X-Ray light can pass through human tissue but cannot pass through bones, thats why x-ray scans can show bones but not tissue or organs.
Gamma - Gamma waves have extremely short wavelengths around 100 picometers which is the size of the nucleus of an atom ( 1 picometer is 1 trillionth of a meter). Gamma waves are released during fusion, fission and nuclear reactions therefore it is very harmful to our body and can cause serious damage.
Microwave - Certain frequencies of microwaves can be absorbed by water molecules and heat them up which means microwaves can be used for cooking and heating food. Although microwaves are also occasionally used to transmit messages.
