- Discuss activity on vibrations and propagation of waves with the help of musical instruments.
Answers
Answer:
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. ... This enables sound to travel much faster through a solid than a gas.
Answer:
The pitch is the degree of highness or lowness of a musical note. The pitch depends on how rapid the vibrations are i.e. how high the frequency is. A higher pitch has a higher frequency.
The diverse sounds made by the instruments in each section of an orchestra are due to harmonics.
Explanation:
Vibrations from the sound source disturb molecules in the medium. The molecules move at the same rate as the sound source. As the vibration travels through the medium each molecule hits another and returns to its original position.
For eg : Percussion instruments
The sound of a percussion instrument comes from striking two things together.
