Answer:
The beat period of the composite wave is 0.11 s.
Explanation:
Given;
frequency of the first sound wave, F₁ = 223 Hz
frequency of the second sound wave, F₂ = 214 Hz
The beat frequency is given as;
Fb = F₁ - F₂
Fb = 223 Hz - 214 Hz
Fb = 9 Hz
The beat period is given as;
[tex]T_b = \frac{1}{F_b} \\\\T_b = \frac{1}{9} \\\\T_b = 0.11 \ s[/tex]
Therefore, the beat period of the composite wave is 0.11 s.
