This light, however, is only one type of electromagnetic radiation.

Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum.

This mysterious radiation had the ability to pass through many materials that absorb visible light.

X-rays also have the ability to knock electrons loose from atoms.

Light is the by-product of the constant jiggling, vibrating, hurly-burly of all matter.

More The word light usually makes one think of the colors of the rainbow or light from the Sun or a lamp.

The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.

Electromagnetic radiation travels in waves, just like waves in an ocean.

The results from Chandra help explore high-energy phenomena and provide insights into the Universe's structure and evolution.
