A metal foot ruler is held at the edge of a table. It is pressed at its free end and then released. It vibrates.
(a) Name the vibrations produced.
(b) State one way to increase the frequency of these vibrations.
Answer
(a) The vibrations produced are known as damped vibrations.
(b) If we place the ruler partially off the table then a shorter length of the ruler is free to vibrate, hence the frequency of vibration increases. The shorter the length of the ruler, the higher the frequency of its natural vibrations.
