Reflection strength is a measure of the total energy of a reflection, manifested in reflection amplitude. It is independent of phase. Reflection strength is also referred to as the instantaneous amplitude, or envelope amplitude. Analysis within specific reflectors can give us clues to changes in lithology or [[porosity]].
