Asound wave has a frequency of 425 hz. what is the period of this wave? 0.00235 seconds 0.807 seconds 425 seconds 850 seconds

Answer : Time period of the wave is 0.002355 per second.

Explanation :

It is given that,

Frequency of the sound wave, f = 425 Hz

Frequency of a wave is defined as the number of vibrations per second.

We know that the relation between the frequency of a wave and the time period is :

The correct option is (A).

Hence, this is the required solution.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
