It is 299,792,458 meters per second. The speed of light in a vacuum is the same for all observers, regardless of their motion relative to the light source.<\/p>\n<p>The speed of light in a medium, such as water or glass, is slower than the speed of light in a vacuum. This is because the light waves interact with the atoms and molecules in the medium. The amount of interaction depends on the properties of the medium, such as its density and refractive index.<\/p>\n<p>The refractive index of a medium is a measure of how much light is slowed down by the medium. The refractive index of water is 1.33, and the refractive index of glass is 1.52. This means that light travels 1.33 times slower <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> in water than in a vacuum, and 1.52 times slower in glass than in a vacuum.<\/p>\n<p>The speed of light is minimum in a vacuum.
