Question

the frequency of the given sound is 1.5 kilohertz how many vibration it is completing in one second

Answer 1

hi friends

The frequency of the given sound is 1.5 kilohertz how many vibrations it is competing in one second?

no. of vibrations = 1.5 kilohertz

1.5×1000=1500
the answer is 1500 per second.

thank you 
i hope this will helps you

Answer 2

Given:

• The frequency of the sound = 1.5 kHz = 1500Hz.
• Time = 1 s

To Find:

• The number of vibrations in one second.

Solution:

The formula to find the frequency is,

⇒ Frequency = No: of vibrations/time

Rearrange the above equation to find the number of vibrations. We get,

⇒ No: of vibrations = frequency×time

Substitute the given values in the above equation. We get,

⇒ No: of vibrations = 1500×1  { multiply the values}

⇒ No: of vibrations  =  1500 vibrations.

∴ The total number of vibrations per second = 1500 vibrations.
