Electromagnetic waves are waves of electricity and magnetism that are created when charged particles, like electrons or protons, accelerate.
Since the sun is so hot, the electrons in the sun are moving around (and accelerating) like crazy, so they emit electromagnetic waves.
We like to call most of the electromagnetic waves that reach earth "Light".
Sound and water waves require something to travel through, like air or water, because they're mechanical waves (they need to move matter around to keep going). However, EM waves don't require any medium. This is because an EM wave has two components: a magnetic part and an electric part. It's complicated to explain, but to sum it up they work together in such a way so that they can rely on each other to travel through space.
If you're really curious about how light works, pick up an introductory physics book, or check out the Wikipedia article on "Electromagnetic Radiation".
To make the volume of a vibrating object louder, you can increase the amplitude or size of the vibration. This will result in a greater displacement of the air particles, producing a louder sound. Additionally, you can position the vibrating object closer to a resonant surface, such as a wall or table, to amplify the sound.
Static electricity produced by friction occurs when two surfaces rub together and electrons are transferred from one surface to the other, causing one surface to become positively charged and the other negatively charged. This charge separation creates an imbalance of electric charge, leading to static electricity buildup.
The ejection of electrons from a surface is determined by the energy of the incoming photons or particles. If the energy is high enough, it can overcome the binding energy of the electrons in the material, causing them to be ejected.
Transmission electron microscopes (TEM) transmit electrons through a thin sample to create a detailed image of its internal structure, while scanning electron microscopes (SEM) scan a focused beam of electrons across the surface of a sample to create a 3D image of its topography. TEM is used for detailed imaging of internal structures at a nanometer scale, while SEM is used for surface imaging and analysis.
Static electricity is produced when two different materials come into contact and then separate, causing a transfer of electrons between the two materials. This transfer of electrons creates an imbalance in the electrical charge on the surface of the materials, resulting in static electricity.
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
If the surface area of the vibrating body is decreased, the loudness of the sound will also decrease. This is because less energy is being transferred to the surrounding air, resulting in a quieter sound.
A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
Most kinds of drums have a skinhead ha the vibrating surface that makes the sound.
Proteins are produced in ribosomes.Ribosomes give surface for it
Yes, a surface that loses electrons become positively changed. It becomes a cation

The production of x rays is a reverse process of photoelectric effect. X rays are produced when target metal is bombarded by electrons while in photoelectric effect, the electron are produced when light waves are incident on a metal surface.
Sound, waves on the surface of water (sea), light, a vibrating guitar string etc...

This charge separation creates an imbalance of electric charge, leading to static electricity buildup.
Some things that produce waves include vibrations of particles or objects, such as sound waves produced by vibrating vocal cords or ocean waves generated by wind blowing across the surface of water. Electromagnetic waves are produced by accelerating electric charges, like in the case of light waves emitted by the sun or radio waves emitted by a transmitting antenna.
