Yes, but it is only a slight difference.
In glass, light will go somewhat slower than in a vacuum. Air is almost like a vacuum, with respect to the speed of light - some difference still exists, though.In glass, light will go somewhat slower than in a vacuum.

Ah, such a lovely question. The difference in wavelength between light traveling in a vacuum and light traveling in air is very small. You see, air has a refractive index close to 1, so the difference is generally quite minimal. Just like how we all paint our own colorful landscapes, light paints its beautiful spectrum no matter the medium it travels through.
I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.
Speed of light is max. in vaccum and slower in air.
The speed of light is slower in water than in air. In a vacuum, light travels at about 186,282 miles per second, but in water it slows down to about 140,000 miles per second.
The speed of gamma radiation in air or vacuum is approximately the speed of light, which is about 299,792,458 meters per second.
That depends what it comes out of. If it passes into air from vacuum, thenits speed decreases. If it passes into air from water or jello, then its speedincreases.
The speed of light is a maximum in a vacuum. In other media, such as air or water, the speed of light is slower due to interactions with the medium's particles.
The speed of light is much faster than the speed of sound. Light travels at approximately 186,282 miles per second in a vacuum, while sound travels at about 1,125 feet per second in air.

Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
