**Transmission line wavelength (λ) calculator** - step by step calculation, formula & solved example problem to find the wavelength of the lossless transmission line. Velocity of propagation (U) & sinusoidal frequency (f) are the key elements of this calculation. Wavelength is a wave between any two points. Velocity of propagation (VoP) is the speed of wave propagation, also known as velocity factor (VF). Sinusoidal wave frequency is the number of complete sine wave cycle per second.

The below mathematical formula is used in this calculator to find the wavelength (λ) of the transmission line

The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations to find the wavelength (λ) of the transmission line.

**Example Problem**

Find the wavelength (λ) of the transmission line whose velocity of propagation U = VoP = 3 x 10^{8} m/s & sinusoidal frequency f = 1000 Hz.

**Solution**

The given data

velocity of propagation U = VoP = 3 x 10^{8} m/s

sinusoidal frequency f = 1000 Hz

__Step by step calculation__

Formula to find (λ) = U/f

substitute the values in the above formula

= 3 x 10^{8}/1000

**(λ) = 3 x 10 ^{5} meters**
