Write an essay on the processing of sensory information by the auditory and visual systems.
Within your essay you should:
- Describe how light and sound waves are able to initiate activity in their respective sensory receptors.
- Explain how the receptors for each system are able to differentiate between different wavelengths of signal.
- Briefly compare what type of information (about the external environment) can be inferred from the wavelength of light and sound waves to help us make sense of our external environment.
