- You can see distant stars.
- You can feel the warmth of the sun on your face.
- You can use radio to communicate with astronauts on the moon and rovers on Mars.
Electromagnetic waves are known to travel through vacuum based on empirical evidence and theoretical knowledge in physics. This is supported by experiments such as the Michelson-Morley experiment and the behavior of electromagnetic radiation in space. Additionally, electromagnetism is a fundamental force in nature with well-established properties, including the ability to propagate through vacuum.
Sound requires a solid, liquid or gas to carry the vibrations in waves. The air in the atmosphere is actually a collection of gases and so sound travels through what appears to be an empty space. Sound cannot travel through a vacuum so an explosion two meters away from you in space would be silent (but probably still hurt!)
One way to prove that sound can travel through solids is by conducting an experiment where a solid material, such as a metal rod or a wooden block, is used to transmit sound waves. By striking one end of the solid material and observing the sound wave produced at the other end, one can demonstrate that sound can indeed travel through solids. Additionally, conducting similar experiments with different solid materials can further support the idea that sound propagation occurs in solids.
Heinrich Hertz discovered radio waves in 1887 while conducting experiments to prove the existence of electromagnetic waves predicted by James Clerk Maxwell's theory. His work laid the foundation for the development of wireless technology.
Yes, the molecules are able to vibrate, thus relaying the sound vibrations through a solid mass. When we hear sounds through a wall we prove this concept. The sound vibrates the air outside the room then the wall and then the air inside the room and finally our eardrum which is also a solid.

good question, unfortunately nobody really knows! Initially, scientists assumed it was travelling through some undetected medium which they called the ether. But no one managed to prove it. Now scientists just say that it is a self-propagating wave of oscillating electric and magnetic fields, so it doesnt need a medium to travel through.

Because experiments and technology have enabled us to prove the electromagnetic spectrum extends beyond the narrow band of visible light.
That it is a part of the electromagnetic spectrum
Simply put, light travels in straight lines. If you want to prove this, look at a beam of light coming from a small torch, or find a tube or hose. You can see through the tube when it's straight, but if it's bent, you can't see anything.

Yes, you can travel with your old passport after naturalization, but it is recommended to also carry your naturalization certificate to prove your citizenship.
It is rare and difficult to prove a hypothesis true or false through experimentation. While it is typically easy to prove something completely false, proving it true is another story.
Unlike the P-wave, the S-waves, or shear waves, cannot travel through liquids, and this causes a shadow zone for S-waves opposite to where they originate(caused by the molten outer core of the Earth).
