Light Year is defined as the distance travelled by light in one year.
And correcting you, light travels not light year. So there is speed of light.
Speed of light is different in different mediums.
Speed of light in a vacuum is -: 2.99 x 10^8 ms^-1
Speed of light in air = 2.99 x 10^8 / 1.003 = 2.981 x 10^8 ms^-1
Speed of light in water = 2.99 x 10^8 / 1.333 = 2.2431 x 10^8 ms^-1
