What is the relationship between frequency and wavelength in sound waves?

What is the relationship between frequency and wavelength in sound waves?

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.

What is the formula to calculate frequency?

The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m).

What is the pendulum’s frequency?

Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!

How can a pendulum be used to measure G?

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find “g.” This is your measured value for “g.” Repeat the above procedure for 3 more cases.

How can the accuracy of a pendulum experiment be improved?

Improve the accuracy of a measurement of periodic time by:

1. making timings by sighting the bob past a fixed reference point (called a fiducial point )
2. sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.

What are the sources of error in simple pendulum experiment?

The possible sources of errors come from errors in measuring the period T using a stopwatch and errors in measuring the precise length of the string using a ruler or a meter stick. The surrounding air resists the rate of swinging of the pendulum and causes errors in the value of the period.

How would you go about taking the most precise measurements of a pendulum swinging?

A simple way to measure the pendulum’s period fairly precisely is to start the pendulum swinging, and measure the time required for a large number of FULL swings – 40, 50, or so. Choose the number of swings so that the total time for the measurement is 40 seconds or more.
