Opque not able to be seen through
ligth absorption a process where the energy of photons is taken up by an object, typically converting the light's energy into heat.
transverse waves a wave where the particles of the medium vibrate at a right angle (90 degrees) to the direction of the wave's propagation, or energy transfer.
wave lengths the distance over which a wave's shape repeats, typically measured as the distance between two consecutive corresponding points of the same phase, like two adjacent crests or troughs.
amplitude the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
speed of light The speed of light is the speed at which light, and all other electromagnetic radiation, travels through a vacuum.
light year a long distance or great amount.
electromagnetic spectrum The electromagnetic (EM) spectrum is the full range of all types of electromagnetic radiation, organized by frequency and wavelength.
visible light that you can see the light even if if it is reflecting through a mirror it is still visible
gamma rays Gamma rays are a form of high-energy, short-wavelength electromagnetic radiation, meaning they have the shortest wavelengths and highest energy of all electromagnetic waves.
radio waves Radio waves are a type of electromagnetic radiation with the longest wavelengths and lowest frequencies in the electromagnetic spectrum, ranging from about a millimeter to over 100 kilometers.
xrays they are used to see if any bones are broken in your body and used if you are extremly hurt.
infared waves a form of electromagnetic radiation with wavelengths longer than visible light, making them invisible to the human eye.
micro waves a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves.
ultraviolet rays a type of electromagnetic radiation that has shorter wavelengths than visible light.
