Final answer:
Baffles are devices that divide a tank into several smaller tanks. In physics, baffles are often used in applications such as fluid mechanics and wave interference.
Step-by-step explanation:
Baffles are devices that divide a tank into several smaller tanks. In physics, baffles are often used in applications such as fluid mechanics and wave interference. For example, in a ripple tank, which is used to study wave behavior, baffles can be placed to create a two-dimensional interference pattern by vibrating in tandem.
