Definition for waves
Question | Answer |
---|---|
Waves- | Is a disturbance that moves throught matter or space. |
Transverse Waves- | Causes particles in matter to move back and forth along right angles |
Compressional Waves- | Cause particles in the matter to move back and forth alone te same directionin which the wave travels. |
Wavelength- | Shows how the wavelengths of verse and compressional. |
Frequency- | Is the number of wavelenghts that passes by a point each second. |
Law of Reflection- | The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal. |
Refraction- | Is the change in direction of a wave when it changes speed. |
Diffraction- | Is the bending of waves around an object. |
Intensity- | Amount of energy that a wave carries post a certain area each second. |
Pitch- | Is the human perception of the frequency of sound. |
Reverberation- | Are repeated echoes. |
Electromagnetic Waves- | Are waves that can travel throught matter or empty space. |
Electromagnetic Spectrum- | Is the complete range of electromagnetic wave frequency is in wavelength. |
Infared Waves- | Waveslengths between 0.001 meters and 700 billionths of a meter. |
Ultraviolet Waves- | Wavelengths between about 400 billionths and 10 billionths of a meter. |
