The frequency of the infrared wave at the given speed and wavelength is [tex]5.5 \times 10^{13} \ Hz[/tex].
The given parameters;
- speed of the wave, v = 3 x 10⁸ m/s
- wavelength of the wave, λ = 5.5 μm
The frequency of the infrared wave is calculated by using wave equation as shown below;
v = fλ
where;
- f is the frequency of the wave
[tex]f = \frac{v}{\lambda} \\\\f = \frac{3\times 10^8}{5.5 \times 10^{-6}} \\\\f = 5.5 \times 10^{13} \ Hz[/tex]
Thus, the frequency of the infrared wave at the given speed and wavelength is [tex]5.5 \times 10^{13} \ Hz[/tex].
