light travels faster in vacuum.
true
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Light travels much faster than sound - about a million times faster. When an event happens at a distance, light reaches your eyes almost instantly, allowing you to see it first. Sound, on the other hand, travels much slower, taking some time to reach your ears, which is why you hear the event after seeing it.
Light is faster than sound. Light travels through empty space at a speed of about 186,282 miles per second (299,792 kilometers per second), whereas sound travels through air at about 1,125 feet per second (343 meters per second).
We see the firework works first because the because burning emits light . It is a fact that it travels faster than sound . So the sound energy produced during the burning of fire work reaches us late . So we hear the sound after vizualizing it.
Nothing travels faster than light.
lightning travels faster. Light is faster than sound.
There is nothing that travels faster than light.

Blue light travels faster in crown glass compared to red light.
Light. No ordinary matter can travel at or faster than the speed of light.
The speed of knowledge/information travels faster than the speed of light.
Light appears lighter, and also travels faster, than sound.
Light travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
Nothing within the known laws of physics can travel faster than light in a vacuum. However, certain theoretical particles known as tachyons are hypothesized to travel faster than light. Additionally, gravitational waves can also travel at the speed of light.
