In summary, light can travel faster than sound. This is because light travels through a vacuum, such as space, while sound needs a medium, such as air, to propagate. Light also has a higher frequency and shorter wavelength, allowing it to travel at a much faster speed. However, the speed of light and sound can vary depending on the medium they are traveling through. In general, light travels at a much faster speed than sound, making it possible to see lightning before hearing the accompanying thunder.
