14. What is the FREQUENCY of a sound wave that has a wavelength of 6 meters and a speed of \( 1300 \mathrm{~m} / \mathrm{s} \) in Jell-o?

To find the frequency of a sound wave, you can use the formula: \( f = \frac{v}{\lambda} \), where \( f \) is the frequency, \( v \) is the speed of sound in the medium, and \( \lambda \) is the wavelength. Given the speed \( v = 1300 \, \mathrm{m/s} \) and the wavelength \( \lambda = 6 \, \mathrm{m} \), you can calculate the frequency as follows: \[ f = \frac{1300 \, \mathrm{m/s}}{6 \, \mathrm{m}} \approx 216.67 \, \mathrm{Hz} \] So, the frequency of the sound wave in Jell-o is approximately 216.67 Hz. Did you know that sound travels at different speeds through various materials? Jell-o is notably slower than air, which is about 343 m/s at room temperature. This peculiarity in speed can make sound waves take on quirky characteristics when traveling through more viscous mediums like Jell-o, which can be fun to explore in sound experiments! When dealing with frequency and wavelength, a common mistake is to confuse the units or misapply the formula. Always make sure that your wavelength is in meters and speed is in meters per second! If you accidentally switched units, you might end up with a frequency that doesn't make sense. It's essential to double-check your calculations!
