Unit 8 Mechanical Waves Test 13 of 20 The wavelength of a radio wave with a frequency of 102.7times 10^4 Hz is: 2.92 m 3.43times 10^-3 2.92times 10^10 m 2.92times 10^2

To find the wavelength of a radio wave with a frequency of $102.7\times 10^{4}$ Hz, we can use the formula:<br /><br />Wavelength = Speed of Light / Frequency<br /><br />The speed of light is approximately $3.00\times 10^{8}$ m/s.<br /><br />Plugging in the values, we get:<br /><br />Wavelength = $3.00\times 10^{8}$ m/s / $102.7\times 10^{4}$ Hz<br /><br />Wavelength = $2.92\times 10^{2}$ m<br /><br />Therefore, the correct answer is $2.92\times 10^{2}$ m.
