Waves
Question | Answer |
---|---|
Compressional Wave | mechanical wave that causes particles in matter to move back and forth along the direction the wave travels |
law of reflection | states that the angle the incoming wave makes with the normal to reflecting surface equals |
pitch | The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. |
refraction | Change in direction of propagation of any wave as a result of its traveling at different speeds at different points along the wave front. |
frequency | The rate at which something occurs or is repeated over a particular period of time or in a given sample. |
intensity | The quality of being intense: "the pain grew in intensity". |
wave | A long body of water curling into an arched form and breaking on the shore. |
wavelength | The distance between successive crests of a wave, esp. points in a sound wave or electromagnetic wave. |
ultraviolet wave | (Ultraviolet waves) Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light |
electromagnetic spectrum | Of or relating to the interrelation of electric currents or fields and magnetic fields. |
electromagnetic waves | (electromagnetic wave) electromagnetic radiation: radiation consisting of waves of energy associated with electric and magnetic fields. |
diffraction | The process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture. |
reverberation | echo: the repetition of a sound resulting from reflection of the sound waves; "she could hear echoes of her own footsteps". |
transverse waves | A wave vibrating at right angles to the direction of its propagation. |
infrared waves | (infrared wave) A wave with a frequency between 300 GHz and 400 THz; usually used for short-range communications. |
