A wave of infrared light has a speed of 6m/s and a wavelength of 12 m. What is the frequency of this wave? 0.5 Hz 2.0 Hz 18 Hz 72 Hz

To find the frequency of the wave, we can use the formula:<br /><br />Frequency (f) = Speed (v) / Wavelength (λ)<br /><br />Given:<br />Speed (v) = 6 m/s<br />Wavelength (λ) = 12 m<br /><br />Substituting the given values into the formula:<br /><br />Frequency (f) = 6 m/s / 12 m<br />Frequency (f) = 0.5 Hz<br /><br />Therefore, the frequency of the infrared wave is 0.5 Hz.
