Question

b) the velocity of sound is........................
1) wavelength x frequency 2) temperature x pressure 3) ​

Answer 1

Answer:

1) Wavelength x Frequency.

Explanation:

we know,

speed = distance / time.

i.e. speed = distance x 1 / time

but in case of sound wave,

distance = wavelength & frequency = 1 / time.

so the formula becomes:-

Speed = Wavelength x Frequency.

Answer 2

Answer:

1) wavelength x frequency

Explanation:

ok
