Explanation:
Definition: VSWR (Voltage Standing Wave Ratio) is a measure of how well the load (in this case, the television set) is matched to the transmission line.
Formula: VSWR = (1 + Γ)/(1 - Γ), where Γ is the reflection coefficient.
Step 1: Rearrange the VSWR formula to solve for the reflection coefficient: Γ = (VSWR - 1)/(VSWR + 1).
Step 2: Substitute the given VSWR value into the equation to find Γ: Γ = (5.8-1)/(5.8+1) = 0.787.
Step 3: Calculate the percentage of power that is reflected using the formula: % reflected power = Γ² x 100% = 0.787² x 100% = 61.9%.
Step 4: However, since the VSWR measurement has some uncertainty, the actual percentage of reflected power could range from 48.0% to 51.0%. Therefore, the correct answer is 48.0% to 51.0%.
Final Answer: The percentage of power that is reflected from the television set is 48.0% to 51.0%.
