Why there is no sound year like light year?
The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
Do mirrors work in outer space?
Yes, mirrors work in outer space. They reflect light just like they do on Earth. However, objects placed in front of a mirror in space may not appear as they do on Earth due to the lack of atmosphere and different lighting conditions.
What does a vacuum in space contain?
Vacuum we mean that there is nothing in the space. But perfect vacuum is not possible even in space as there are some traces of hydrogen molecules. More over space itself is having some properties such as magnetic permeability and electric permittivity. So space is considered as a medium through which light could travel. But sound cannot travel as it needs material medium. Hence sound waves are called as mechanical waves where as light waves are named as electromagnetic waves.
How does the sun's heat get to planets far away?
Heat from the Sun travels through the vacuum of space in the form of electromagnetic radiation - primarily through infrared which has wavelengths longer than visible light; some of the visible light also gets converted to heat when it hits the planet (the darker the surface, the more pronounced this effect is).
The speed of light is 300000000 in a vacuum.Does it always have this speed?
The speed of light is exactly fixed at 299,792,458 m/s in the vacuum of freespace. It is an important physical constant usually denoted by the symbol c0. There is nothing faster. Light has always this speed in a vacuum, but it slows down when it travels through something, like glass, water, or air ... The greater the density of the matter that light is travelling through, the slower light travels.
What effect does the vacuum of space have on the universe?
It really has no effect because a vacuum people say that a vacuum is just like a black hole it is but it is basically it reflects light!
What does light do in empty space?
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.
Does light travel fastest in space in air in water or through glass?
Light travels fastest in a vacuum, such as in space. It slows down when passing through different mediums like air, water, and glass due to interactions with atoms and molecules in those materials, which cause the light to refract and bend.
What is the name of an area in space that acts like a vacuum cleaner?
A black hole is an area in space that acts like a vacuum cleaner, exerting a strong gravitational pull on surrounding matter and light. This gravitational force is so powerful that not even light can escape from it, giving it its characteristic black appearance.
Why there is no sound year like light year?
The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
What kind ot enerny can go though a emtpy space?
Electromagnetic energy, such as light, can travel through empty space. This is because light does not require a medium, like air or water, to propagate. It can travel through the vacuum of space due to its wave-like nature.
Which wave source can travel through a vacuum if space?
Electromagnetic waves, such as light and radio waves, can travel through a vacuum like space because they do not require a medium to propagate. This is because they consist of oscillating electric and magnetic fields that can travel through empty space.
How does a satellites move in space when its vacuum?
well space is like a vacuum you cant escape it and sound wave do not travel in space but space isn't literally a vacuum so they move by rockets and the gravity of earth
Does light create a shadow in the vacuum of outer space like it does on the earth?
Shadows are caused by something BLOCKING the light. You can have shadows in space, if something is blocking the light. On Earth, shadows often look fuzzy; this is caused by the Sun's light being scattered in the air. In space, there is nothing to scatter the light, so shadows are sharp-edged and clear.
What is energy that can be transferred through empty space?
Electromagnetic radiation, such as light or radio waves, can transfer energy through empty space due to the properties of electromagnetic fields. This form of energy does not require a medium like air or water to travel through, allowing it to propagate through the vacuum of space.
What of these waves can NOT travel through the vacuum of space?
Sound waves cannot travel through the vacuum of space because they require a medium, such as air, water, or solids, to propagate. Electromagnetic waves, like light and radio waves, can travel through the vacuum of space because they do not require a medium.
What is a stick with a fire at one end of it and rhymes with scorch?
Ah, that sounds like a torch! A torch is a wonderful tool used to light up the darkness and guide our way. Just like how a little light can brighten a painting, a torch can brighten our path in the night.
