Explain the terms: a) Frequency (f) b) Wave length (λ) c) Amplitude (A) d) Time period (T)
Understand the Problem
The question is asking for explanations of specific terms related to waves, including frequency, wave length, amplitude, and time period. This requires defining each term in the context of wave physics.
Answer
Frequency: Wave cycles per second. Wavelength: Distance per wave cycle. Amplitude: Maximum displacement. Time period: Duration per cycle.
a) Frequency (f): The number of complete wave cycles that pass a point in one second. Measured in Hertz (Hz).
b) Wavelength (λ): The distance between consecutive points of a wave, such as crest to crest, measured in meters.
c) Amplitude (A): The maximum displacement of points on a wave, indicating the wave's energy.
d) Time period (T): The time taken for one complete cycle of the wave, calculated as the inverse of frequency.

d) Time period (T): The time taken for one complete cycle of the wave, calculated as the inverse of frequency.
More Information
Frequency is measured in Hertz (Hz), indicating wave cycles per second. Wavelength tells the physical length of one cycle, while amplitude reflects wave energy. The time period is inversely related to frequency.
Tips
A common mistake is confusing frequency and time period; remember, frequency is the number of cycles per second, while the time period is the duration of one cycle.
