What else can I help you with?
Is the speed of light in space varies with wavelength?
No, it does not.
Why do black holes attract light?
According to the particle theory of light, light is made us of particles called photon. Black hole has very high gravity. Its escape velocity being more than that of speed of light, light is attracted towards it and it even cannot escape by lunizah: black holes attract every thing even the light because they have a very strong attractive force and that's the reason why black holes attract light!! ^_^
What is the speed of light near to the event horizon of a Black hole?
The speed of light is a constant, it does not matter in or out of a black hole.
Do black holes move at the speed of light?
No, black holes do not move at the speed of light. While they can exert a strong gravitational pull, their movement is not necessarily tied to the speed of light.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Can the speed of light escape a black hole?
No, the speed of light cannot escape a black hole because the gravitational pull of a black hole is so strong that even light cannot escape it.
What is the speed of light as it travels through transparent objects?
The speed varies according to the refractive index of the objects.
Can the speed of light be the same in all media?
The speed of light varies, depending on the medium. It also varies a bit depending on the frequency. The speed of light in different materials is less than the speed of light in empty space. When physicists talk about the speed of light being an absolute limit, they're talking about the speed of light in a vacuum. It's perfectly possible for material objects to travel faster than light in a particular medium ... for example, electrons emitted by radioactive elements (beta rays) often move faster than the speed of light in water.
What is the rotation speed of black holes?
as high as 98.7% of the speed of light
Why does the speed of light vary?
The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
Can light escape black holes?
No. The escape velocity of a black hole is greater than the speed of light.
Is the speed of light effected by black holes?
Nope.. Light always travels at the same speed. However, black holes do affect the trajectory of the photons, hense diverting the direction of the light.
