In the context of the auditory system, the was developed to overcome the limitations of the frequency theory.

Volley theory

Explanation:

Frequency theory states that humans perceive sound based on patterns of time to which the neurons respond to sound in the cochlea. So the properties of sound like pitch of a pure tone is perceived by the neuron firing pattern. Frequency theory proposed that only one neuron was firing at a rate that mimics the frequency of the sound. This is not true, so a theory in which proposed that groups of neurons were responsible was born called Volley theory.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
