QuestionAnswer
compressional wave mechanical wave that cause particles in matter to move back and forth along the direction the wave travels
diffraction bending of waves around an object
electromagnetic spectrum complete rang of electromagnetic wave frequency and wavelength
electromagnetic waves waves that can travel matter or empty space, includes radio waves, X rays, and gamma rays
frequency numbers of wavelength that pass a given point in one second, measured in hertz
infrared waves electromagnetic waves with wavelengths between about one thousandth of a meter and 700 billionths of a meter
intensity amount of energy a wave carries past a certain area each second
law of reflection states that the angle the incoming wave make with the normal to the reflecting surface equals the angle the reflected wave make with the surface
pitch human perception of the frequency of sound
refraction change in direction of a wav when it change speed as it travel from one material into another
reverberation repeated echoes of sound waves
transverse wave mechanic waves that causes particles in matter to move at right angles to the direction the waves travels
ultraviolet waves electromagnetic waves with wavelength between about 400 billionths and 10b
waves Disturbance between that move through matter and space and carries energy
