why sound wave are called as longitudinal wave?
a sound wave has a frequency of 2KHz and wavelength 35 cm.how long it will take to travel 1.5km?
what are the avantages and disadvantages of echo and reverberation?
what are the si unit of amplitude,freqency&wavelength
WHAT KIND OF ENERGY TRANSFORMATION TAKES PLACE IN THE FOLLOWING DEVICES
A stone is dropped into a well, 44.1 m deep. The sound of the splash is heard 3.13 s after the stone is dropped. Find the velocity os sound in air .
SOUND IS A TRANSVERS WAVE. TRUE OR FALSE. PLEASE EXPLAIN
ALSO PLEASE EXPLAIN TRANSVERSE WAVE AND LONGITUTIDNAL WAVE WITH DIAGRAMS AND EXAMPLES
I want to make a SUPW project please give me some simple ideas.
write all formula's in chapter sound ... and defines...???
reverberation? How can it be reduced?
a source of sound is placed at one end of an iron bar 2km long and 2 sounds are heard at the other end at an interval of 5.6 s. if the velocity of sound in air is 330m/s , find the time taken by sound to travel 2 km in iron and the velocity of sound in iron.
A solid weighs 50 gf in air and 44 gf in when completely immersed in water. Calculate(i) the upthrust (ii) volume of the solid and (iii) the relative density of the solid
A tuning fork is vibrating at a rate of 30720 times per minute. I f the velocity of sound is 332 m/s , calculate
(a) the frequency of vibration in hertz
(b) the wavelength of the wave produced.
establish the relationship between speed of sound, its wavelength and frequency?
