The speed of light in empty space is constant, i.e., always the same. However, the speed of light in another medium can change. So, if a planet has a denser atmosphere than Earth, the speed of light will probably be slightly less than here.

∙ 12y agoYes. To be more precise, the acceleration is different on different planets. For example, on Earth, acceleration is 9.8 meters/second/second (usually expressed as meters/second2), meaning that each second, the speed will increase by 9.8 meters/second (assuming air resistance can be neglected, of course), while on Mars, acceleration due to gravity is 3.7 meters/second2.

Is speed of light and speed of sound different in different materials?
yesthe speed of light in a vacuum is different than the speed of light in our atmosphere or another planets atmospherethe speed of sound is also different in the air than when it goes through a solid or liquidAddional answerThe first answer above not quite correct. The speed of light is the same regardless of what it passes through. It's 186,282 miles per second, but there is a small change due to the refractive index of different materials. But this difference is much less than the difference of the speed of sound in different materialsIf we go even further, it's the same to all observers (as Einstein would say). That means that even if you were travelling at close to the speed of light, it would appear to be travelling past or towards you at the speed of light. Now we're into relativity!
Does the speed of light differ?
The speed of light is different in different media; light travels more slowly in water than it does in air, for example.
What is the speed of planets?
The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
Why wavelenth changes with speed of light?
Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.
Does the wavelength and frequency of light changes when it enters glass from air?
Nothing. The speed changes. We live in a universe where electromagnetic waves change frequency if they can't change speed (and in a vacuum they can't), and only change speed if they enter another medium like glass.
When do light waves change speed?
speed of light is different for materials of different refractive index and also higher the refractive index lesser will be speed of light in that medium. so if light travels from rarer to denser medium (with respect to refractive index) then light waves will change their speed
What is the change in speed called when light travels through different mediums?
It is simply called a change in speed.
What planet have speed of light?
i don`t think planets travel at the speed of light

What happens to light as it passes through different mediums?
Its speed and wavelength change.

When light enters a medium with a different refractive index they change speed or direction?
yes , if the light travel from less density to more density the speed will decrease , the direction will change depend on the entered angle
Does the wavelength and frequency of light changes when it enters glass from air?
Nothing. The speed changes. We live in a universe where electromagnetic waves change frequency if they can't change speed (and in a vacuum they can't), and only change speed if they enter another medium like glass.
How does the speed of light change in jello?
Light travels through different substances at different speeds. The speed will changeas it enters jello from something else, and again as it leaves jello and enters somethingelse. While the light is in the jello its speed is constant. A few on-line resources that wechecked gave that speed as roughly 217,400,000 meters per second. That's about73% of the speed of light in vacuum.
How can the speed of a light wave be changed?
If you shine light through a different medium, its speed will change. It's faster in a vacuum than in air, which is faster than in a denser gas, etc.
