The formula to calculate the frequency is: ๐‘“ =๐‘ฃ*๐œ† f=ฮป*v where ๐‘ฃ is the speed of sound and ๐œ† is the wavelength. Given: ๐‘ฃ = 343 m/s ๐œ† = 44 cm = 0.44 m ฮป=44cm=0.44m Plugging in the values: ๐‘“ = 343 / 0.44 โ‰ˆ 779.55 Hz The period of a wave is the reciprocal of the frequency: ๐‘‡ = 1/๐‘“ T= 1/779.55Hz โ‰ˆ 0.00128s(or 1.28 ms)
