1. What are the different properties of sound waves?
Ans. Sound waves have properties such as frequency, amplitude, wavelength, and speed of propagation.
2. How does sound travel through different mediums?
Ans. Sound can travel through solids, liquids, and gases by vibrating the particles in the medium.
3. What is the relationship between pitch and frequency of sound waves?
Ans. Pitch is determined by the frequency of sound waves, with higher frequencies corresponding to higher pitches.
4. How is the intensity of sound measured?
Ans. The intensity of sound is measured in decibels (dB) using a logarithmic scale to quantify the loudness of sound.
5. What is the Doppler effect and how does it affect sound waves?
Ans. The Doppler effect is the change in frequency of sound waves as the source or observer moves, leading to shifts in pitch perception.
