We are using radio waves to send messages to outer space.
Electromagnetic energy travels through space in the form of waves, known as electromagnetic waves. These waves consist of electric and magnetic fields that oscillate perpendicular to each other as they propagate through space. The energy is carried by these waves and can travel through a vacuum, such as outer space, without the need for a medium.
Those two descriptions are not mutually exclusive, and in fact, electromagnetic waves do both.
No. light waves required no medium for transmission.
Sound waves require a medium to travel through, such as air, water, or a solid object. In outer space, there is a lack of air or any other medium for sound to propagate. Therefore, sound waves cannot travel in the vacuum of space.
Sound requires a medium (such as air, water, or solids) to travel because it relies on the vibration of particles to transmit energy. In outer space, the vacuum environment lacks these particles, and hence, sound waves have no medium to propagate through. This results in an absence of sound in space.
Electromagnetic waves are waves which can travel through the vacuum of outer space.
outer space
A shout is carried across by sound waves in the air. Outer space has no atmosphere and there is no medium to carry sound waves; therefore a shout will not be heard.
No air. Sound is vibration is something- most commonly air, but sometimes water, metal, etc. There is no air in outer space to be vibrated.
They use radio waves which are a type of electromagnetic waves. Electromagnetic waves can travel through a vacuum Ligth is a type of electromagnetic wave and that travels through space from the sun and the stars.
Self propagating electro-magnetic waves. Otherwise known as light waves.
No. In vacuum, all electromagnertic waves have the same speed.
Sound waves do not leave the planet. They cannot travel in the vacuum of outer space
Electromagnetic eaves are waves that can travel through the vacuum of outer space. Microwaves, x-rays, and TV are all kinds of electromagnetic waves.
Space craft send messages electronically via radio waves. And these actually move through a vacuum better then through the atmosphere.
Sound waves travel through matter. The only thing it doesn't travel through is vacuums or outer space.
Karl Jansky discovered radio waves coming from outer space in 1932. This discovery led to the field of radio astronomy and revolutionized our understanding of the universe by allowing scientists to study celestial objects using radio telescopes.
