Electromagnetic radiation.
Light travels best through empty space because there are no particles to absorb or scatter the light. In contrast, matter can diminish the speed and intensity of light as it interacts with particles and undergoes absorption and scattering.
In empty space, light travels in a straight line at a constant speed of approximately 299,792 kilometers per second. It does not require a medium to propagate, which is why light can travel through the vacuum of space.
Electromagnetic energy can travel through empty space and travels in waves. This includes visible light, radio waves, microwaves, X-rays, and gamma rays.
Electromagnetic waves, such as light and radio waves, can travel through empty space. These waves do not require a medium to propagate, allowing them to travel through the vacuum of space.
Electromagnetic energy, such as light and heat, travels by radiation. Radiant energy can move through empty space and is transmitted by electromagnetic waves.

Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).

Electromagnetic waves, such as light and radio waves, can travel through empty space. These waves do not require a medium to propagate, allowing them to travel through the vacuum of space.
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
Electromagnetic energy, such as light and heat, travels by radiation. Radiant energy can move through empty space and is transmitted by electromagnetic waves.
Light travels through empty space as electromagnetic waves, with no need for a medium to propagate. These waves consist of oscillating electric and magnetic fields that can travel across the vacuum of space at the speed of light. This is a fundamental property of light and is one of the key principles of modern physics.
Refraction
The phenomenon where light travels through the lens of a telescope is called refraction. Refraction occurs when light passes through a medium like glass, causing the light rays to bend and converge or diverge to form an image.
If light travels through an object, it is still called light. If you want to specify, you might say "light travelling through an object".
One example would be X-Rays. They are stopped by Lead, but travel through other matter and empty space.
