Sound waves are mechanical waves that require a medium, such as air, water, or solids, to propagate. The frequency of a sound wave refers to the number of complete oscillations or cycles it makes per second and is typically measured in Hertz (Hz). Human hearing ranges from approximately 20 Hz to 20,000 Hz.
On the other hand, light waves are electromagnetic waves that can propagate through a vacuum, such as space, and do not require a medium. The frequency of light waves is much higher than that of sound waves. The spectrum of visible light, which our eyes can perceive, ranges from about 430 trillion Hz (terahertz) to 770 trillion Hz (terahertz), corresponding to different colors from violet to red.
In summary, light waves have a much higher frequency range than sound waves. The key difference lies in their nature and propagation mechanisms, with sound waves being mechanical and requiring a medium, while light waves are electromagnetic and can travel through a vacuum.
