Question
A trumpet needs to be blown to make sound. What vibrates to make this sound?
- Membrane
- String
- Trumper
- Air column
Hint:
The trumpet is made to produce sound by blowing.
The correct answer is: Air column
A trumpet needs to be blown to make sound. Air column vibrates to make this sound.
- In the wind instruments, such as the flute and trumpet, vibrating air makes the sound.
- The air particles move back and forth creating sound waves. i.e. the vibration made by blowing travels as an oscillation in the trumpet.
- As the oscillation travels in the air column of the trumpet, it produces sound.
