Light travels in photons which have wave and particle characteristics and so they do not need a medium to travel through. In classical physics, light is illustrated as a type of electromagnetic wave. In modern quantum physics, the electromagnetic field is described by the theory of quantum electrodynamics (QED). In this theory, light is expressed by the fundamental excitations (or quanta) of the electromagnetic field, called photons. In QED, photons are massless particles and thus, according to special relativity, they travel at the speed of light in vacuum.
What else can I help you with?
How can light or radio waves pass through the nothingness of space and isn't that evidence of a somethingness?
light and radio waves are energy themselves, so they are not dependent on "something" being there to travel through as sound is. the reason that sound cannot pass through a vacuum is because it is a set of energy waves that flow through the molecules of the substance. causing the first molecule to bump into the second, second into the third, third to the fourth and so on.
Is a window non luminous?
Yes, a window is typically non-luminous because it does not emit light on its own. Its purpose is to allow light to pass through it into a space, rather than generate light itself.
Why is sunlight more dangerous in outer space than on earth?
Sunlight is more dangerous in outer space than on Earth because there is no matter in space, unlike on Earth, so sunlight just passes through the emptiness of space and shines in all directions. When light passes through matter, it takes longer for the light to pass through it to reach something. In space, it only takes 8 minutes for sunlight to reach Earth's surface. The speed of light also depends on what type of matter the light is going through.the sun is more hotter in space than the earth
Can gamma rays travel through empty space?
Yes, gamma rays can travel through empty space because they are a form of electromagnetic radiation like light. They are the most energetic form of electromagnetic radiation and can pass through most materials, including empty space, due to their high penetrating power.
How do you know light can travel through outer space?
Light can travel through outer space because it propagates as electromagnetic waves, which do not require a medium to travel through. This means that light can move through the vacuum of space without any obstacles. This property of light allows it to travel vast distances from its source, such as from stars to telescopes on Earth.
What is the Medium through which light and magnetism pass through in space?
A vacuum
What does light pass through on its way to earth?
Light passes through the vacuum of outer space as it travels from the sun to the Earth. It does not require a medium such as air or water to propagate.
How can UV light be transmitted without a fiberoptic cable?
Just like visible light, UV (ultraviolett) light can also pass through empty space, or air.
What type of material always lets light pass through it?
Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.
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.
What do you call an object which light can not pass through?
An object through which light cannot pass is known as opaque.
Can light pass through styrofoams?
Some light is allowed to pass through, but not all, making it translucent.
What type of glass allows some light to pass through it?
A Transparent glass !!
Does light pass through objects?
sometimes it pass through objects
Can light pass through cellophane paper?
Yes, light can pass through cellophane paper. Cellophane paper is a translucent material, which means it allows some light to pass through but scatters the light as it does so.
Do visible and infrared light pass through the same types of materials?
No, visible light and infrared light do not pass through the same types of materials. Visible light can pass through materials like glass and water, while infrared light can pass through materials like plastic and some fabrics.
What happens to light when it travells through air and meets a transparant surface?
transparent surfaces, allow light to pass through, translucent surfaces allow SOME light to pass through and opaque surfaces DO NOT allow any light to pass through
