Answer:

The wavelength of the wave is [tex]5.45\times 10^5\ m[/tex] and time period is 0.0018 s.

Explanation:

The given question is, "A wave whose frequency is equal to 550 Hz, propagates in the air. What is its wavelength and its period?"

Given that,

The frequency of a wave, f = 550 Hz

The time period of a wave,

[tex]T=\dfrac{1}{f}\\\\T=\dfrac{1}{550}\\\\T=0.0018\ s[/tex]

Wavelength,

[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{550}\\\\\lambda=5.45\times 10^5\ m[/tex]

So, wavelength of the wave is [tex]5.45\times 10^5\ m[/tex] and time period is 0.0018 s.
