The speed of light is always the same, the different speeds associated with a liquid are due to the absorbing and emitting of the light within the substance as it travels through it, which is not necessarily 'c' (2.99792458x10^10 cm/sec).
it travels fast in gases
refractive index is the measure of how how fast or slow light travel through a material reference to the speed of light in empty space.
They all travel through a vacuum at the same speed - The speed of light.
light travels faster.
Sound cannot travel through a vacuum.
Copper is opaque to light - light can not travel though it.
it travels fast in gases
it travels fast in gases
ans2. Light is an electromagnetic phenomena, and is unaffected by the motion of air.
Light goes incredibly fast through space, bouncing off objects.
Yes, they travel some fast!
670 616 629 mph
That actually varies, depending on the specific liquid.
depending on the nature of the solid liquid or gas. usually gas the fastest followed by liquid than solid.
refractive index is the measure of how how fast or slow light travel through a material reference to the speed of light in empty space.
the speed of light
3.00 x 108/ 1.49 = 2.0134 x 108 m/s Therefore light will travel through acrylic at 2.01 x 108 m/s.
