What are the wavelength, frequency, time period and amplitude of a sound wave?
Wavelength(λ): Wavelength is defined as the distance between two consecutive compressions or rarefactions of a sound wave.
Frequency(v): Frequency is the number of complete oscillations per unit time.
Time period(T): The time taken by two consecutive compressions or rarefactions to cross a fixed point is called the time period of the sound wave.
Amplitude(A): The magnitude of the maximum disturbance in the medium on either side of the mean value is called the amplitude of the wave.
How does the sound produced by a vibrating object in a medium reach your ear?
Explain how is sound produced by your school bell.
Suppose you and your friend are on the moon. Will you be able to hear any sound produced by your friend ?
Why are sound waves called mechanical waves?
