what is the speed of a sound wave if its frequency s 160 hertz and its wavelength is 2.2m?
what is speed? it's m/s
wavelength is in m.
frequency is in 1/s
so, speed = wavelength * frequency = 160*2.2 m/s
Think about it. If each wave extends 2.2m, and there are 160 of them every second, than that means the wave travels at 2.2*160 meters every second.
To find the speed of a sound wave, you can use the formula:
Speed = Frequency × Wavelength
Given that the frequency is 160 Hz and the wavelength is 2.2 m, you can substitute these values into the formula to find the speed:
Speed = 160 Hz × 2.2 m
Multiply the frequency (160 Hz) by the wavelength (2.2 m):
Speed = 352 m/s
Therefore, the speed of the sound wave is 352 meters per second.
