Study Notes
Wave Characteristics
Amplitude
- The maximum displacement of a wave from its equilibrium position
- Measured in units of distance (e.g., meters, centimeters)
- Larger amplitude waves have more energy
- Example: A wave with a larger amplitude will have a higher "crest" and a lower "trough"
Frequency
- The number of oscillations or cycles per second
- Measured in units of hertz (Hz)
- Higher frequency waves have more oscillations per second
- Example: A wave with a frequency of 20 Hz completes 20 cycles in one second
Speed
- The distance traveled by a wave per unit time
- Measured in units of distance per unit time (e.g., meters per second, kilometers per hour)
- Depends on the medium in which the wave is traveling
- Example: The speed of light in a vacuum is approximately 299,792,458 meters per second
Interference
- The superposition of two or more waves resulting in a new wave pattern
- Can be either constructive or destructive
- Constructive interference: Waves combine to form a wave with a larger amplitude
- Destructive interference: Waves combine to form a wave with a smaller amplitude
- Example: When two waves with the same amplitude and frequency are in phase, they produce a wave with a larger amplitude (constructive interference)
Wavelength
- The distance between two consecutive points on a wave that are in phase
- Measured in units of distance (e.g., meters, centimeters)
- Related to frequency and speed by the equation: wavelength = speed / frequency
- Example: A wave with a frequency of 20 Hz and a speed of 4 meters per second has a wavelength of 0.2 meters
