During a school experiment, a bell is struck repeatedly. The bell completes 600 complete vibrations in 3.0s. The wavelength of the sound produced is measured to be 0.50m. Using this information, answer the following.
(i) Calculate the frequency of the sound produced by the bell.
(ii) Determine the time period of one vibration.
(iii) Using the data above, find the speed of sound in the air of the laboratory.
