… each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is T = 2π Square root of√ L/ g, where L is the length of the pendulum and g is the acceleration due to gravity.

Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f. … The Speed of Sound. a. one-ninthb. one-thirdc. the same asd. three times larger thanThe Speed of Sound – The Physics Classroom www.physicsclassroom.com › class › sound › Lesson-2 › The-Speed-of-So…
Read moreWhat is frequency of sound in physics?
The frequency of a sound wave not only refers to the number of back-and-forth vibrations of the particles per unit of time , but also refers to the number of compressions or rarefactions that pass a given point per unit of time.
Read moreHow do you find the frequency of sound?
To calculate the frequency of a wave, divide the velocity of the wave by the wavelength . Write your answer in Hertz, or Hz, which is the unit for frequency.
Read moreHow do you find the relative frequency?
To find the relative frequencies, divide each frequency by the total number of students in the sample –in this case, 20. Relative frequencies can be written as fractions, percents, or decimals. Cumulative relative frequency is the accumulation of the previous relative frequencies.
Read moreWhy do we calculate relative frequency?
Frequency is a way to measure how often a particular event occurs. Relative frequency on the other hand is a way to measure how often a particular event occurs against total occurrences .
Read moreDoes period equal 1 over frequency?
The period is simply the reciprocal of the frequency . In this case, the period is 1/(51.2 Hz) which is 0.0195 seconds.
