Because the speed of light is always constant; it doesn't change based on the movement of the source or detector or the direction in which it travels.
The double-slit experiment and the theory of electromagnetism both demonstrate that light can propagate through a vacuum where there is no medium for it to travel in. This has been further confirmed by the speed of light being constant in a vacuum according to Einstein's theory of relativity.
Light can travel in a vacuum without the need for a medium. This is because light is composed of photons which do not require a medium, unlike other types of waves such as sound waves that do need a medium to propagate.
Light can travel through a vacuum, which means it does not require a medium to propagate. This is explained by the wave-particle duality of light. While light behaves as a wave and doesn't need a medium, it can also be understood as a stream of particles called photons.
No, a medium is not required for light waves to be transmitted. Light waves can travel through a vacuum, such as outer space, without the need for a medium.
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
This statement is not accurate. Electromagnetic waves, such as light and radio waves, can travel through a vacuum where there is no medium. They do not require a physical medium like air or water to propagate.

Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
Mechanical waves such as sound and vibration require a medium in which to travel. Electromagnetic waves such as radio and light need no transmission medium.

Light is composed of particles called photons that can travel through empty space because they do not require a medium to propagate. This is due to the wave-particle duality of light, where it behaves both as a wave and a particle, allowing it to travel through vacuum without the need for a medium like air or water.
Sounds need a medium to travel, such as air, water, or solid materials. As sound waves pass through the medium, they cause particles to vibrate, transmitting the sound energy from one point to another. Without a medium, such as in a vacuum, sound waves cannot travel.
