Introduction

The speed of sound is a fundamental concept in physics that plays a crucial role in various fields, including acoustics, physics, and engineering. It is the rate at which a sound wave propagates through a medium, such as air, water, or solids. The speed of sound is influenced by several factors, including the frequency and wavelength of the sound wave. In this article, we will explore the relationship between the speed of sound, frequency, and wavelength, and calculate the speed of sound with a frequency of 15 Hertz and a wavelength of 22 meters.

The Relationship Between Speed, Frequency, and Wavelength

The speed of sound is related to the frequency and wavelength of a sound wave through the following equation:

v = fλ

Where:

v is the speed of sound
f is the frequency of the sound wave
λ is the wavelength of the sound wave

This equation is a fundamental principle in physics and is used to calculate the speed of sound in various media.

Calculating the Speed of Sound with a Frequency of 15 Hertz and a Wavelength of 22 Meters

To calculate the speed of sound with a frequency of 15 Hertz and a wavelength of 22 meters, we can use the equation above. Plugging in the values, we get:

v = fλ v = 15 Hz × 22 m v = 330 m/s

Therefore, the speed of sound with a frequency of 15 Hertz and a wavelength of 22 meters is approximately 330 meters per second.
