1)The period of these ripples will be 0.2 sec.
2)The time period of sound wave will be 100 Hz.
3)The frequency of the sound wave will be 5×10⁶ Hz.
<h3>What is frequency?</h3>
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
Frequency is given by the formula as,
Frequency of ripples (f₁)=5 Hz
The period of these ripples will be;
T₁=1/f₁
T₁=1/5
T₁=0.2 sec
The time period of sound wave (T)=0.01 seconds
The time period of sound wave;
f=1/T
f=1/0.01
f=100 Hz
Time period of A radio wave = 0.0000002 seconds
The frequency of the sound wave is;
f=1/T
f=1/0.0000002
f=5×10⁶ Hz
Hence,the period of these ripples will be 0.2 sec.
