Do ultraviolet waves travel at the speed of light in a vacuum?
Ultraviolet and visible light waves all travel at the same speed whenever they're all traveling through the same material.
Do electromagnetic waves all travel at the same speed through space?
Through a vacuum ... yes. Through outer space, which is not quite a vacuum ... not quite, but very very close.
Does time always move at a constant speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
Does a photon obey the rules of something traveling at the speed of light?
Obeying PhotonsPhotons by definition travel at the speed of light. They are unaffected by mass dilation since they have no mass, but are affected by time dilation: a photon could conceivably travel "forever" from our point of view since no time would pass from a photon's reference frame. So yes, they follow the rules along with everything else.
Do all em eaves travel at the same speed?
Electromagnetic waves have the same speed when travelling through a given medium: Air, water, vacuum,...
Do ultraviolet waves travel at the speed of light in a vacuum?
Ultraviolet and visible light waves all travel at the same speed whenever they're all traveling through the same material.
How fast does light travels through water?
The speed of light is a universal constant through a vacuum meaning it is traveling through zero resistance and it travels in a straight line. If you do an experiment and send a photon through water(pure H^2O) a set distance of lets say 1 meter the photon will travel to the end point slower than in the vacuum of space. Think about it light is effected by gravity, when it passes near the earths it changes direction towards the earth there is so much stuff in water that this happens to light at frequent rates, so the light takes longer to get to the end point but its actual travel speed is the same as in a vacuum. Think about it this way 2 people are both running at 8 miles an hour. Each person has the same start point and the same end point . the distance to the end point is 1mile. person A travels in a straight line. person B zig zags. You see although both are traveling at the same speed person A gets there faster. if the pressure and density of a liquid is identical than the travel speed of light from start to finish is the same in all experiments but regardless the final distance take much more time than in a vacuum.

Space is a vacuum and continuous bombard of bodies in space happens all the time producing light and sound. Light travels through a vacuum but what about sound?
Sound is mechanical energy. It is created in a number of ways, but they are all mechanical in nature. Something (a mass or some material) must move. The mechanical energy of sound is carried by the medium through which it is traveling. The mechanical energy is actually transferred into the medium through which it is going to travel. As such, sound cannot travel through the "nothing" that is space. Light is electromagnetic energy. It's like radio waves, but higher in frequency. It is a moving electric and magnetic field, both, and at the same time and at right angles from one another. It is affected by the medium through which it is traveling, but not by a vacuum. It is unaffected by a vacuum. Light and other forms of electromagnetic energy blow through the vacuum of space like there was nothing there.
What wave form can pass through empty space?
Compression waves, such as sound, cannot move through space due to the lack of a medium. Transverse waves, such as light and radiation, can move through a vacuum such as space. This is related to Einstein's theory of relativity, in which he states that Mass and Energy are the same thing. Essentially, transverse waves, which move at the speed of light, are moving fast enough to metaphorically be their own medium, as stated by the equation E=MC2 (Energy traveling at the speed of light is what we call a photon, which is a very hard concept to explain. The best I can do off the top of my head is that it's almost like it's matter and energy at the same time). Since the energy is it's own medium, the energy can travel through a vacuum, where there is no other medium to support it.
Do electromagnetic waves all travel at the same speed through space?
Through a vacuum ... yes. Through outer space, which is not quite a vacuum ... not quite, but very very close.
Does speed of light increase as the wavelength of a light wave increase?
No. All wavelengths of light, and all other forms of electromagnetic waves too, all travelat the same speed, just as long as they remain traveling through the same stuff.
Which light has the ACCURATE speed?
ANY light traveling through the same medium (stuff) has the same speed.
Does time always move at a constant speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.

What type of light travels the fastest?
In a vacuum all wavelengths of light travel at the same speed, c. In other mediums the speed of light is dependent on the refractive index of that material; v=c/n where v is the speed through the medium and n is the refractive index. The refractive index if different for different materials and can have fairly complex dependence on the wavelength of light. The fastest type of light is therefore dependent on the medium through which it is travelling.
