What is the approximate audible range of frequency for humans?
What is the approximate audible range of frequency for humans?
Ans: – The approximate audible range of frequency for human is 20HZ to 20KHZ.
Which sound wave will have its crests farther apart from each other – a wave with frequency 100 or a wave with frequency 500?
Ans: – As we all know, v=ny or v/n=y, here y= wavelength, v=velocity, n= frequency. So, it is clear that which have less frequency will be more wavelength as we all the more creates also.
If the velocity of sound is 330 metres per second (ms–1), what will be wave length if the frequency is 1000 Hertz?
Ans: – We know, v=ny,
Here, v=velocity= 330m/s, n=frequency= 100Hz, y=wavelength=?
So, y= 330/100 = 0.33m.
