What do light waves propagate through?
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
Why light can pass through empty space?
Basically, light is NOT a mechanical wave, which would require matter; it is an electromagnetic wave, which means that disturbances in the electric field and the magnetic field propagate. This requires no matter; such fields exist - and can propagate - in empty space.
How are sound waves the same as water waves and light waves?
I can provide a partial answer. Sound waves differ from light waves in at least one crucial respect: a sound wave can only propagate through a physical substance - through "stuff". While a light wave can also propagate through a physical substance (e.g. glass), it can also propagate through a vacuum (a sound wave cannot do this). There are other differences as well, but perhaps other posters can provide those.
How sound waves differ from light waves?
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.
Is anything produced in addition to light?
heat is produced

What is the speed of gravitiy?
Gravitational waves propagate at the speed of light. Any change in the distribution of masses will propagate at that speed.
Why call light as E M wave which is not having neither electric nor magnet?
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

What is the difference between sound and visiblle light in transmission?
Sound will propagate through any matter, but not a vacuum, light will propagate through a vacuum, but only through transparent matter.
Does light propagate around electromagnetic fields in a vacuum?
It is not very clear what the question means. Light is an electromagnetic field and it can propagate in a vacuum. Propagation of a beam of light is unaffected by any other electromagnetic fields in its path.
What is an epicenter and how do shockwaves produced an earthquake travel?
The epicenter is directly above the point where an earthquake originated. Shock waves are produced and propagate spherically along the epicenter.
Why speed of light is greater than speed of sound?
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.

Is the James Maxwell discover that light is transverse elecromagnetic wave?
Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light. Therefore, he also suspected that light was an electromagnetic wave. This was confirmed later.Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light.

How do heat and light propagate?
In matter heat is the vibration (kinetic energy) of atoms or molecules and propagates in matter by means of conduction and convection.Heat is also radiation and part of the electromagnetic spectrum which includes visible light. Thus heat and light are propagated in a vacuum as radiant energy, synchronized oscillations of electric and magnetic fields that propagate at the speed of light.
What happens when light travels through vacuum?
Nothing. It continues to propagate at the speed of light, and is not diffracted or distorted except by negligible gravitational effects.
What is propagate?
To propagate is to increase and spread by means of reproduction.
