Study Notes
Wave Characteristics
- Waves are propagating, oscillating deformations of quanta or mediums.
- Examples include water waves (transverse), sound waves (compression), and electromagnetic waves (transverse, oscillating electric and magnetic fields).
Wave Frequency
- Frequency describes the number of wave cycles per unit time (e.g., per second).
- Higher frequency = more cycles/second, shorter wavelengths.
- Lower frequency = fewer cycles/second, longer wavelengths.
- Frequency in light relates to color (violet highest).
- Frequency in sound relates to pitch.
Frequency Formula
- Frequency (f) = 1 / Period (T)
- Measured in Hertz (Hz), where 1 Hz = 1 cycle/second.
Wave Period
- Period (T) is the time for one complete wave cycle.
- Period (T) = 1 / Frequency (f)
Wave Amplitude
- Amplitude (A) measures the energy carried by a wave.
- For transverse waves, amplitude is the distance from the rest position to the crest or trough.
- For longitudinal waves, amplitude is expressed as pressure (e.g., pascals, decibels).
- Amplitude for electromagnetic waves is expressed as volts per meter or as brightness.
Amplitude vs. Frequency
- Amplitude and frequency are independent.
- Waves with the same frequency can have different amplitudes (e.g., same color light but different brightness).
- Likewise, waves with the same amplitude can have different frequencies (e.g., different pitches at same sound level).
