Final answer:
The traveling wave pattern according to Bekesy is characterized by crests and troughs completing one cycle. The wavelength is the horizontal length covered by one cycle. When water waves pass through gaps similar in width to the wavelength, an interference pattern is produced.
Step-by-step explanation:
The traveling wave pattern according to Bekesy is characterized by a series of crests and troughs, which complete one cycle. The horizontal length covered by one cycle is called the wavelength. When water waves pass through gaps or openings similar in width to the wavelength of the waves, an interference pattern is produced, resulting in alternating bright and dark regions.
