Use of Ultrasonic Sound
To clear the dirt of clothes: The clothes can be washed by the modern washing machine. Mixing soap or powder soap with water the clothes…
What is Audibility Range?
We know, the sound is not produced without vibration. If an object vibrates at least 20 times per second then the sound produced from that…
Explain Variation of Velocity of Sound
It takes some time when sound reaches our ear from its source. The distance travelled by sound in one second is called velocity of sound.…
Explain Uses of Echo
When a sound becomes dividing from its unique sound and is repeated due to reflection then this reflected sound is called echo. Theoretically, an echo…
What is Echo?
If anyone produces a sound standing near the bank of a river, many of us have the experience of hearing the repetition of that sound…

We know that the sound is a power. This power is circulated through the wave. The sound wave is a longitudinal wave. During the circulation…
Explain the Relation between Frequency and Time Period
We know that the number of complete vibrations of a vibrating particle in one second is called its frequency. Frequency is denoted by f. Again…
Explain Relation between Wave Velocity and Wavelength
