Question

A sound travels with the speed of 340m/s if its wavelength is 1.3cm calculate the frequency of the sound wave . Also calculate the time taken for 1 complete vibration of sound wave

Answer 1

HEY DEAR YOUR'-:-) --ANSWER:-) :-) :-) :-)


Apply this to waves: count the number of waves passing each second (= frequency), and multiply by the length of each (= wavelength) to find the speed. speed = distance/time = l/T= l / (1/f) = f λ. Work through three examples: A simple example, perhaps for sound in air, with values in Hz and m.'-:-) :-) ---:-) :-)



Once the speed (of sound) in a medium is determined the above mentioned equation expresses the relation between the (sound) frequency and the wavelength. Given the frequency of the wave, the wavelength is equal to the speed (of sound) in the medium divided by the frequency.

:-) :-) :-) :-) The speed of sound waves in air is 340 m/s. Determine the fundamental frequency (1st harmonic) of a closed-end air column that has a length of 67.5 cm.:-) :-) :-) :-) :-) -----

Answer 2

The given data is
speed of sound =340 m/s
wavelength = 1.3 cm
c = wavelength x frequency
340 = 1.3 x f
f =340/ 1.3
frequency= 2.61 x 10 ^4 Hz
where
f= frequency
c= speed of sound
wavelength
