Electromagnetic Spectrum and Light Waves Crossword Puzzle

QUESTIONS LIST:

• microwaves : a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter
• spectrum : electromagnetic _ - all possible frequencies of electromagnetic radiation
• reflection : an amount of light, heat, or sound that is reflected by a body or surface
• ultraviolet : electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than x-rays
• x rays : very energetic form of electromagnetic radiation that can be used to take images of the human body
• radio waves : type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light
• visible light : rainbow spectrum of light
• wavelength : distance between successive crests of a wave
• refraction : change in direction of wave propagation due to a change in its transmission medium
• infrared radiation : electromagnetic radiation that produces a sensation of heat emitted by hot objects. intermediate in energy between visible light and microwaves, its wavelength range is about 750nm to 1mm
• absorption : process or action by which one thing absorbs or is absorbed by another
• frequency : the number of waves that pass a fixed point in unit time
• gamma rays : extremely high-frequency electromagnetic radiation and therefore consists of high-energy photons
