How do signals travel in space?
Signals travel in space using electromagnetic waves, such as radio waves or light. These waves can travel through vacuum without a medium and carry information encoded in their frequency, amplitude, or phase. Communication between spacecraft and Earth, for example, is achieved by transmitting signals through space using antennas and receivers.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
What is the isosphere?
The isosphere is a hypothetical shell in space surrounding a planet or star, within which electromagnetic signals travel at the speed of light. It is used in theoretical discussions about communication in space and how signals propagate through different media.
How can the command centre communicate with the space ship in space if outer space is a vacuum?
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.
What type of material can travel through space?
Sound and Light can travel through space.
What type of electromagnetic signals are currently used to communicate through space?
Radio waves are the most commonly used electromagnetic signals for communication through space. These waves have long wavelengths that can travel long distances without getting absorbed by the Earth's atmosphere. Additionally, microwaves and infrared signals are also used for specific space communication purposes.
What can infrared travel through?
Infrared radiation can only travel through empty space or transparent objects
Why can television satellites which broadcast information as electromagnetic radiation send signals from the vacuum of space?
i should imagine its because EM waves can travel through a vacuum so that's why it is possible for satellites to broadcast information from impulse signals sent from outer space

What type of waves travel through space?
Sound waves cannot travel through space.
Can a black hole travel through space?
Yes, a black hole could travel through space.
What can travel through space without a(n) medium?
Electromagnetic waves can travel through space without a medium.
