define the following terms and in each case give the symbol and the unit:
-wavelength
-frequency
-period
-velocity
1. Wavelength:
- Symbol: λ (lambda)
- Unit: meters (m)
- Definition: Wavelength is the distance between corresponding points on adjacent waves. It is usually measured from crest to crest or trough to trough.
2. Frequency:
- Symbol: f
- Unit: Hertz (Hz)
- Definition: Frequency is the number of complete cycles of a wave that occur in a second. It represents the rate at which the waves are oscillating or vibrating.
3. Period:
- Symbol: T
- Unit: seconds (s)
- Definition: Period is the time taken for one complete cycle of a wave to occur. It is the reciprocal of frequency; thus, T = 1/f.
4. Velocity:
- Symbol: v
- Unit: meters per second (m/s)
- Definition: Velocity is the rate at which a wave propagates or travels. It is the product of wavelength and frequency, represented by v = λf.
