The incident and reflected waves are related to each other through a transmission line parameter called

• 
  Reflection coefficient

• Reflection Current

• 
  Standing waves

• Incident current

The ratio of the maximum to minimum magnitudes of voltage or current on a line having standing waves is called

• Standing wave ratio

• Smooth line

• Reflection Coefficient

• surge impedance

The loop resistance per unit length of the transmission line is

• Capacitance
