how many vibrations will a tuning fork of frequency 280 hz will complete during the time sound travels forward in air by 18 cm.speed of sound in air be 336 m/sec
how is echo formed?????????
The roof and walls of the auditorium are generally covered with sound absorbent materials like compressed fibreboard or draperies. Why is it so?(
Why are sound waves known as mechanical waves?
The frequency of a source of sound is 100 Hz . How many times does it vibrate in a minute?
What are the uses of multiple reflection of sound ?
on what factor does the quality of a sound depend?
Explain how a human ear works
Why bryophytes and pteridophytes grow in moist and shady places? plzz tel me anyone
Name three devices which work on the reflection of sound
WHAT KIND OF ENERGY TRANSFORMATION TAKES PLACE IN THE FOLLOWING DEVICES
a source of sound produces 20 compressions and 20 rarefractions in 0.2 seconds.the distance between a compression and rarefaction is 50cm . find the wavelength,frequency and time period of the wave.
please do answer it fast cuz tommorow is my finals.
working model for sound as project. can suggest?
A man standing between two parallel cliffs and fires a gun and hears two successive echoes after 4 second and 6 second the distance between the cliffs is (Speed of sound 330 ms-1)
(a) 1600 m (b) 1650 cm (c) 1650 m (d)1590 m
