In a vacuum, EM waves travel at a constant speed, and they travel very fast—about 300,000 kilometers (186,000 mi) per second. In 1 second, an EM wave can travel a distance greater than 7 times the distance around Earth. Even at this speed, rays from the Sun take about 8 min- utes to reach Earth.Click to see full answer. Likewise, can Electromagnetic waves travel through space?Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Electromagnetic waves are created by the vibration of an electric charge.Likewise, how far do radio waves travel on earth? It depends where they travel. In space they can travel very far away, the most distance object from which we received electromagnetic radiation is GN-z11 – Wikipedia, that’s 32 billion light years from us. On the Earth it depends on the propagation mode: Ground wave – up to ~300–500 km. Keeping this in consideration, how do electromagnetic waves travel? Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.How far can Frequency travel?The two-way radios and intercoms available for you to purchase usually fall in the frequency range of 150MHz to 900MHz. Unlike the AM radio waves, radio waves in these frequencies travel in straight lines and as a general rule cannot travel over the horizon or behind solid obstacles.
