Which is the high pitched sound thunder or whistle?
A whistle typically produces a high-pitched sound, while thunder is a deep rumbling noise.
How does a whistle work to produce sound?
A whistle produces sound when air is blown through a narrow opening, creating vibrations that travel through the air as sound waves. The shape and size of the whistle determine the pitch and volume of the sound produced.
What is the sound of a kettle called?
The sound of a kettle boiling is commonly referred to as a whistle or a hiss. It is caused by the steam escaping through the spout or pressure release valve of the kettle.
What energy is wasted when blowing a whistle?
The energy wasted when blowing a whistle is converted to sound energy that is not useful for the intended purpose of the whistle, which is to produce a specific frequency of sound. Inefficient design or improper technique can also contribute to wasted energy.
What do you call an effect where in the pitch of the whistle rises as the train approaches the station and falls off as it moves away?
This effect is called the Doppler effect. It occurs when there is relative motion between the source of a sound (like a train whistle) and an observer. As the train approaches, the sound waves are compressed, resulting in a higher pitch, and as it moves away, the sound waves are stretched, causing a lower pitch.
