    1.What properties of sound determine the volume of sound? Is this affected by the motion of the sound source? 2.What occurs when the pitch increases and the sound source is in motion? Explain your answer. 3. If the pitch of a sound decreases and the sound source is moving, is the sound source moving toward or away from the observer? 4. Describe at least two ways that your understanding of the Doppler effect could be applied to everyday life.

    the property of sound which determines the volume is amplitude The loudness of a sound depends on the wave’s amplitude. here wave is the sound wave. The louder a sound, the bigger the amplitude. This is also a way of measuring the amount of energy the wave has.

    the motion of the sound source does not affect the volume, but it affects the pitch (frequency of the wave)

    the motion of sound source doesn't affects the amplitude.

    the pitch of a sound wave is its frequency. the more the pitch the more is the frequency. when a sound source moves away from u the wavelength is reduced when a sound source moves towards u the wavelength is increased speed of sound is constant we have universal wave equation v=fλ velocity of sound is constant v/f =λ as f(frequency) increases λ(wavelength) decreases as f decreases λ increases

    3- pitch=frequency so when pitch decreases λ increases as we discussed above^ and we also discussed that when a sound source moves away u the λ increases so the sound source is moving away from u

    When a bus or a car moves towards u while blowing horn u hear a loud noise cause the bus(sound source) is moving towards u and thus tbe wavelength gth gets compressed nd u hear a loud noise But when the bus crosses u nd goes away that time the wavelength increases nd the noise is low
