The absolute refractory period refers to that time during which a stronger stimulus will lead to the generation of a new action potential

The relative refractory period coincides with the hyperpolarization phase of the action potential.

The relative refractory period refers to that time during which a stronger stimulus will lead to the generation of a new action potential

The refractory period is caused by the hyperpolarization phase of the action potential.

The refractory period is important in preventing the overlap of succeeding action potentials
