Answer to Question 1

Answer: Beats are the sequence of alternating reinforcement and cancellation (constructive and destructive interference of two sets of superimposing waves differing in frequency, and heard as a throbbing sound. Beats have a frequency of their own equal to the difference between the two wave frequencies. Beats are evident when a pair of slightly mismatched tuning forks is sounded, and when a pair of whining diesel engines run side by side.

Answer to Question 2

Answer: When the vibrating tuning fork is held against a table, the large area of the table is forced into vibration. Compared with the surface area of the bare tines of a tuning fork, the larger area of the table sets a greater amount of air into vibration, which in effect amplifies the sound of the vibrating tuning fork.
