    Hello

    I have the VSWR question and I'm not sure how to solve this Reflected power.

    The formula for VSWR is this
    VSWR=(1+√Pref÷Pin)÷(1-√Pref÷Pin)

    and VSWR is 1.5 and power input is 40.8W

    the question is to solve the Power Reflected and i'm not sure how to do the steps.

    Help me :)

    Also. It looks like you got the formula wrong. Pref and Pin should be inside the square root.
