A wave is characterised by the physical parameters:
Correct answer: C. Wavelength, frequency and speed of wave
- A. Amplitude, wavelength and acceleration
- B. Frequency, wavelength and acceleration
- C. Wavelength, frequency and speed of wave
- D. Displacement, wavelength and speed of wave
Explanation
A wave is typically characterized by the following physical parameters:1. Wavelength (λ): The distance between two consecutive points on the wave that are in phase with each other.2. Frequency (f): The number of oscillations or cycles of the wave per second.3. Speed of wave (v): The distance traveled by the wave per unit time.These three parameters are related by the wave equation:v = λf

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
