There are two sets of nerves in your skin. The first type are somatosensory neurons that send sensory information to your central nervous syste. The second set consists of autonomic fibers that control smooth muscle in the skin and the blood vessels in the skin.
Wave Frequency:
<u><em>Wave frequency is the number of waves that pass a fixed point in a given amount of time.</em></u>
How do you find the frequency of a wave?
<u><em>To calculate the frequency of a wave, divide the velocity of the wave by the wavelength. Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T.</em></u>
