Question

Time period of s wave is 5 ×10‐³ what is frequency

Answer 1

Answer:

200Hz

Explanation:

As we know

Frequency = 1/ Time period

freq. =

$1 \div5 \times {10}^{ - 3 } = 1000 \div 5 \\ = 200$

Answer 2

Answer:

The frequency of a sound wave is equal to 2×10²s⁻¹ , when time period of wave is 5 ×10⁻³s.

Explanation:

• Time period of a sound wave is tome taken to produce one wave or the time required to complete one oscillation.
• The frequency of a wave is the number of waves produce in one second or the total number of oscillation of one wave in per unit time. The S.I. unit of frequency is hertz (Hz) or per second.
• Frequency of a wave is the reciprocal of the time period.
• Frequency of a sound wave:

         $f=\frac{1}{\big T}$

We have given the time period of a wave, T =  5 ×10⁻³s

Frequency of wave, $f=\frac{1}{5*10^{-3}s}$

f = 2×10² s⁻¹

Therefore, the frequency of wave is equal to  2×10² s⁻¹.
