Question

The nervous system can distinguish between a light touch and a heavier touch by changing the frequency of impulses sent to sensory centers. Light touch will produce a lower frequency of nerve impulses compared to a heavier touch which will produce a higher frequency of nerve impulses. This change in the frequency of nerve impulses allows the brain to interpret the difference between a light touch and a heavier touch.
