In terms of heat transfer, radiation isthe emission of thermal energy in the form of infrared waves. Generally, thermal radiation and infrared waves are referred to simply as "heat". Since heat is carried by electromagnetic waves, it does not need a physical medium to transfer it. Which body...
Radio waves, on the other hand, are fundamentally different from sound waves.They are electromagnetic:they result from oscillations of the electromagnetic field and don't need a physical medium. So they, like other types of electromagnetic wave, can travel basically anywhere—through a vacuum or ...

Light Travels Fast and Free Light is a rather curious topic in science as there is more than one theory regarding its behavior. It travels faster than anything we know and can travel through empty space. Answer and Explanation:1 Light is energy and travels in waves. All forms of energy on...
They result from oscillations of the electromagnetic field and don't need a physical medium, so they, like other types of electromagnetic wave, can travel basically anywhere, through a vacuum, or through atmosphere or water. Now, radio waves can be detected. ...
The question of how light travels through space is one of the perennial mysteries of physics. In modern explanations, it is a wave phenomenon that doesn't need a medium through which to propagate. According to quantum theory, it also behaves as a collection of particles under certain circumstan...
