Nature of sounds Flashcards
electromagnetic radiation
the energy that electromagnetic travel through matter or space
electromagnetic wave
a transverse wave that involves the transfer of electric and magnetic energy
electromagnetic spectrum
the complete range of electromagnetic waves placed in order of increasing frequency
radio waves
electromagnetic waves with the longest wavelength and the lowest frequ]encies
microwaves
shorter wavelengths and have higher frequencies than radio waves do
radar
a system that uses reflected microwaves that reflect off an object
infrared rays
are electromagnetic waves with wavelengths shorter then those of microwaves
thermogram
a image that shows region of different temperatures in different colors
visible light
electromagnetic waves that you can see
ultraviolet rays
electromagnetic with wavelengths just shorter then those of visible light
x-ray
electromagnetic waves with wavelengths just shorter than those of ultraviolet rays
gamma rays
electromagnetic waves with the shortest wavelength highest frequencies
