Question | Answer |
---|---|
Compressional Wave | Mechanical wave that causes particles in matter to move back and forth along the direction the wave travels. |
Diffraction | bending of waves around an object. |
Electromagnetic Spectrum | complete range of electromagnetic wave frequencies and wavelengths . |
Electromagnetic Waves | waves than can travel matter or empty space, includes radio waves,infrared waves, visible light waves, ultraviolet waves, X ray, and gramma rays. |
frequency | Number of wavelenghts that pass a given point in one second, measured in hertz (Hz) |
infrared waves | Electromagnetic waves with wavelengths between about one thousandth of a meter 700 billionths of a meter. |
intensity | amount of energy a wave carries past a certain area each second. |
Law of reflection | states that the total momentum of objects that collide with each other is the same before and after the collition. |
Pitch | human precipitation of frequency of sound . |
refraction | change in direction of a wave when it changes speed as it travels from one material to another. |
reverberation | repeated echoes of sound of waves |
transerse wave | Mechanical wave that causes particles in matter to moves at right angles to the direction the wave travels . |
ultraviolet waves | electromagnetic waves with wavelenghs between about 400 billionths and 10 billionths of a meter |
wave | disturbance that moves through matter and space and carries energy. |
wavelength | distance between one point on a wave and the nearest point moving with the same speed and dirrection |
