What is the wavelength of infrared radiation with a frequency of 3.85 x 10^12 Hz?

Wavelenght is 7,79x10⁻⁵ m

Explanation:

The equation that connects wavelentgh (λ) and frequency (ν) is:

λ=c/ν

Where c is speed of light (3x10⁸ m/sec) and λ is expressed in lenght's units and ν is expressed in "time⁻¹ " units (for example, sec⁻¹)

According to the details, if we just replace the given value of frequency, we just obtaing wavelenght dа ta:

λ = (3x10⁸ m/sec) / (3,85x10¹² sec⁻¹) = 7,79x10⁻⁵ m
