It depends on the neuron. Some neurons respond better to a pressure stimulus or temperature, light, sound ect. For example the neurons in the retina of the eye, they respond to photons of light, but do not respond to pressure or sound.
That has nothing to do with the speed of light or sound but depends on which parts of the TV are fired up first and how quickly they respond.
The transduction of energy for receptor response depends on the energy being captured. In English, Eyes respond to light, Ears respond to sound.
A sensor is a device that is used to measure something and record it. It can measure heat, sound, light, frequency, or motion and respond to it.
Usually plants respond to light by turning toward it.
Earthworms do not respond to darkness per say, but they do respond to light. although they do not have eyes, they are light sesitive.
