electromagnetic spectrum
What is the electromagnetic spectrum? The electromagnetic spectrum consists of a large group of various types of waves, all which travel at the speed of light. ... There are seven different types of waves in the electromagnetic spectrum which are: Radio Waves Microwave/Radar Infrared Visible Light Ultra-Violet X-rays Gamma rays All electromagnetic waves transmit energy from one place to another, all types of waves in the electromagnetic spectrum travel through the air at 300 million metres per second. Radio Waves Radio waves have the lowest frequencies and the longest wavelength in the electromagnetic spectrum and are mainly used for communication purposes. ... Infrared waves are found just before visible light on the electromagnetic spectrum as it has wavelengths that range from red light to violet. ... Far Infrared: this is when the wavelength is closest to the microwave part of the spectrum and the size if its wavelengths are of a pin head. ... Visible Light Visible light waves are the only waves on the electromagnetic spectrum that we are able to visually see. ... On the electromagnetic spectrum ultraviolet light is divided into three types which are: Near Ultraviolet (NUV): is the light that is closest to visible light on the electromagnetic spectrum. Extreme Ultraviolet (EUV): is the light that is closest to x-rays on the electromagnetic spectrum. ... Gamma rays are found last on the electromagnetic spectrum they carry extremely high frequency waves and large amounts of energy.
