a decrease in the frequency of the sound wave.
Explanation:
When a sound source is moving away from an observer, the observer will hear a lower pitch due to a decrease in the frequency of the sound wave. This is known as the Doppler's effect.
- As the sound source moves closer to the observer, they hear a higher pitch in the reverse process.
- A sound wave transmits vibrational energy from the source to the hearer.
- A sound wave has frequency, amplitude, velocity and wavelength just like other wave types.
- The frequency of a wave is the number of waves that passes through a point at a time.
- This is related to the the wavelength of a wave.
- Waves of a high frequency are known to have short wavelengths and vice versa.
- To hear a low pitch, the source moves away and the wavelength between successive crests and troughs on a wave increases considerably.

The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.
<h3>What is the Avogadro’s number?</h3>
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.
The scientist Josef Loschmidt strengthened the Avogadro’s number by obtaining the number of particles in one cubic centimeter of gas under standard conditions.
