To find the electrical length of the transmission line, we can use the formula:

Electrical length = (2π * frequency * physical length) / velocity factor

First, let's calculate the velocity factor. The velocity factor is given by the formula:

Velocity factor = 1 / √(LC)

Given that L = 10 microH/m and C = 40 pF/m, we can calculate the velocity factor as follows:

Velocity factor = 1 / √(10 * 10^(-6) * 40 * 10^(-12))
= 1 / √(400 * 10^(-18))
= 1 / (20 * 10^(-9))
= 1 / 2 * 10^(-8)
= 5 * 10^7

Now, let's calculate the electrical length using the formula mentioned earlier:

Electrical length = (2π * frequency * physical length) / velocity factor
= (2π * 30 * 10^6 * 0.5) / (5 * 10^7)
= (2π * 30 * 10^6 * 0.5) / (5 * 10^7)
= π * 30 * 10^6 / (5 * 10^7)
= 6π / 5
≈ 3.77

Therefore, the electrical length of the transmission line is approximately 3.77.
