Temperature<\/p>\n<p>The speed of sound in air is proportional to the square root of the temperature. This means that if the temperature doubles, the speed of sound will increase by a factor of $\\sqrt{2}$.<\/p>\n<p>The speed of sound is also affected by the density of the medium through which it is traveling. The denser the medium, the slower the speed of sound. However, the effect of density on the speed of sound is much smaller than the effect of temperature.<\/p>\n<p>The frequency and wavelength of sound do not affect the speed of sound in air. This is because the speed of sound is determined by the properties of the medium through which it is traveling, not by the properties of the sound wave itself.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li><strong>A. Frequency:<\/strong> The frequency of a sound wave is the number of waves that pass a given point in a given amount of time. The frequency of a sound wave does not affect the speed of sound in air. This is because the speed of sound is determined by the properties of the medium through which it is traveling, not by the properties of the sound wave itself.<\/li>\n<li><strong>B. Temperature:<\/strong> The temperature of a medium affects the speed of sound in that medium. The speed of sound is proportional to the square root of the temperature.
