(1) Different types of electromagnetic radiation such as radio waves, microwaves, visible light, and x-rays are associated with specific wavelengths. A spectrophotometer is an instrument that performs ...

Electromagnetic radiation is carried by photons, massless particles that travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the ...

The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

Here we explain what different parts of the electromagnetic spectrum teach us about the universe. Radio astronomy studies cosmic radiation with the longest wavelengths (from less than 0.4 inches ...

The electromagnetic spectrum is a continuous range of wavelengths. The types of radiation that occur in different parts of the spectrum have different uses and dangers - depending on their ...
