Light travels faster than sound. Light travels at 299,792,458 metres per second and sound only travels at about 343 metres per second. That’s why we see lightning before we hear the thunder.

• ### Can light travel faster than the speed of sound?

• Light doesn鈥檛 need a medium to travel. The speed of sound through air is about 340 meters per second. It鈥檚 faster through water and it鈥檚 even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they鈥檙e totally different scales. No information can propagate faster than the speed of light.

• ### How fast does light travel through Air and Space?

• As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. How fast does light travel through air? Air has a refractive index of 1.0003 wavelengths.

• ### What is the speed of sound in meters per second?

• The speed of sound through air is about 340 meters per second. It鈥檚 faster through water and it鈥檚 even faster through steel. Light will travel through a vacuum at 300 million meters per second.

• ### What does light travel fastest through solid liquid or gas?

• Furthermore, what does light travel fastest through solid liquid or gas? As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
