To justify or contradict the statement that the VSWR for a short-circuited transmission line is equal to unity, we can analyze the mathematical equations involved.

VSWR, or Voltage Standing Wave Ratio, is a measure of how well a transmission line is matched to the impedance of the connected devices. It is defined as the ratio of the maximum voltage to the minimum voltage along the transmission line.

For a short-circuited transmission line, the load impedance is zero, which means that the transmission line is perfectly matched to the load. In this case, the reflection coefficient (Γ) is equal to -1, as the entire incident voltage is reflected back towards the source.

The VSWR can be calculated using the reflection coefficient as follows:

VSWR = (1 + |Γ|) / (1 - |Γ|)

Substituting Γ = -1, we get:

VSWR = (1 + |-1|) / (1 - |-1|)
= (1 + 1) / (1 - 1)
= 2 / 0

Here, we encounter a division by zero, which is undefined. Therefore, the VSWR for a short-circuited transmission line is not equal to unity. It is undefined in this case.

Hence, we can conclude that the statement "VSWR for a short-circuited transmission line is equal to unity" is contradicted by the mathematical equations.
