Follow @physics_unplugged | video description 👇 Light travels much faster than sound. That’s why you see lightning before you hear thunder. Here’s a comparison: Speed of Light: About 299,792,458 meters per second (approximately 300,000 km/s) in a vacuum. In air, it slows slightly but remains extremely fast. Speed of Sound: Around 343 meters per second (about 1,235 km/h) in air at room temperature. It varies with temperature, pressure, and the medium (e.g., water, metal). Please DM for credits o

Follow @physics_unplugged | video description 👇 Visualization of Speed of light on the surface of different planets in our solar system. The speed of light is considered a fundamental constant of nature. The value of speed of light in vacuum is 299,792,458 meters per second. This video shows that how fast light travels in cosmic scale. Compared to Earth it is very fast but It can be observed that at the bigger scale like around the Jupiter it seems to be slow. The value of the speed of light is
