Question

pls ans this question with proper reasoning

Answer 1

the sound is producing 1500 sound waves in 3 seconds so it will produce 1500 / 3 is equal to 500 waves in 1 s . so frequency is 500Hz

the wavelength is the distance from one compression to the next compression that is 68×2 CM= 68/100×2 m

velocity = wavelength × frequency
=> (68/100×2)×500=680m/s
