[Sound Frequency and Wavelength]

Introduction:
Sound is a form of energy that travels in waves, and it is characterized by several properties, including frequency and wavelength. Understanding the relationship between sound frequency and wavelength is essential in grasping the fundamentals of acoustics and the perception of sound. In this article, we will explore the concept of sound frequency and wavelength in detail.

I. Definition of Sound Frequency
Sound frequency refers to the number of sound waves passing through a point in one second. It is measured in Hertz (Hz) and determines the pitch or tonal quality of a sound. The higher the frequency, the higher the pitch, and vice versa.

II. Relationship Between Sound Frequency and Wavelength
Sound frequency and wavelength are inversely proportional to each other. The wavelength of a sound wave is the distance between successive points of a wave that are in phase. It is denoted by the symbol λ (lambda) and is measured in meters (m). The wavelength can be calculated using the formula: wavelength = speed of sound / frequency.

III. Speed of Sound
The speed of sound is dependent on the medium through which it travels. In dry air at room temperature, sound travels at approximately 343 meters per second. However, the speed of sound varies in different mediums such as water or solids. For example, sound travels faster in water than in air.

IV. Examples of Sound Frequency and Wavelength Relationships
1. High Frequency, Short Wavelength: A high-pitched sound has a high frequency and a short wavelength. Examples of high-pitched sounds include the chirping of birds or the ringing of a telephone.
