Physics
Grade 10: Wave, Light and Sound
| Term | Definition |
|---|---|
| Pulse: | A single disturbance in a medium. |
| Transverse pulse: | A pulse in which the particles of the medium move at right angles to the direction of motion of the pulse. |
| Amplitude: | The maximum disturbance of a particle from its rest (equilibrium) position. |
| Principle of superposition: | The algebraic sum of the amplitudes of two pulses that occupy the same space at the same time. |
| Constructive interference: | The phenomenon where the crest of one pulse overlaps with the crest of another to produce a pulse of increased amplitude. |
| Destructive interference: | The phenomenon where the crest of one pulse overlaps with the trough of another, resulting in a pulse of reduced amplitude. |
| Transverse wave: | A wave in which the particles of the medium vibrate at right angles to the direction of motion of the wave. |
| Wavelength: | The distance between two successive points in phase. |
| Crest: | Highest point (peak) on a wave. |
| Trough: | Lowest point on a wave. |
| In phase: | Two points in phase are separated by a whole number (1; 2; 3; …) multiple of complete wavelengths. |
| Out of phase: | Points that are not separated by a whole number multiple of complete wavelengths. |
| Period: | The time taken for one complete wave pulse. |
| Frequency: | The number of wave pulses per second. |
| Wave speed: | The distance travelled by a point on a wave per unit time. |
| Longitudinal wave: | A wave in which the particles of the medium vibrate parallel to the direction of motion of the wave. |
| Compression: | A region of high pressure in a longitudinal wave. |
| Rarefaction: | A region of low pressure in a longitudinal wave. |
| Echoes: | Reflections of sound waves. |
| Ultrasound: | Sound with frequencies higher than 20 kHz up to about 100 kHz. |
| Electromagnetic waves: | An accelerating charge when an electric field oscillating in one plane produces a magnetic field oscillating in a plane at right angles to it, which produces an oscillating electric field, and so on. |
| Photon: | A packet of energy found in light. |
