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.
