Think of the word medium as something in between. The word medium — from the Latin adjective medius, “middle” — has several meanings that all center on the idea of being in between.

This medium has the same properties as the Turner paint medium, but it is produced using a synthetic base. Clear, gloss ketone resin based liquid medium, gives a highbuild finish and allows glazing and « àlla prima » paint by accelerating drying.

There is a big difference between what the wave does and what the particles in the medium do. As the wave travels through the medium, the particles of the medium oscillate in response to the wave. In a uniform medium, the wave travels at constant speed; each particle, however, has a speed that is constantly changing.

Mechanical Waves Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

Sound waves can travel through solids, liquids, or gases. The speed of sound depends on the medium. The type of matter that a wave travels through determines the speed of the wave.

The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through.

The different types of waves have different uses and functions in our everyday lives. The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

transverse wave

Light travels slower in a medium than it does in a vacuum, and the speed is proportional to the density of the medium. This speed variation causes light to bend at the interface of two media — a phenomenon called refraction.

Light normally travels in straight lines, but with some clever pre-adjustment, it curves instead.

Light Is Also a Particle! Now that the dual nature of light as “both a particle and a wave” has been proved, its essential theory was further evolved from electromagnetics into quantum mechanics. Einstein believed light is a particle (photon) and the flow of photons is a wave.

Because photons are discrete particles, they have a certain amount of energy, but not a wavelength because they are not waves. Before that, Isaac Newton had claimed that light was really a stream of particles, but he did not have much evidence. Young made a clear case by demonstrating that light interferes with itself.

Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed. …

Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely “no”: the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Light is made of particles called photons, bundles of the electromagnetic field that carry a specific amount of energy. With sufficiently sensitive experiments, you can count photons or even perform measurements on a single one.

Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.

The strong force and you. The Higgs field gives mass to fundamental particles—the electrons, quarks and other building blocks that cannot be broken into smaller parts.

Electrons have mass because they interact with higgs field. If it were massless, then it would be called as a photon or a gluon which are the messenger particles or force carriers. Every particle has 0 mass at the beginning. Particles gain more mass when the interaction with the field is more.

Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, there’s no reason why they’d have to be. Not only are all electrons the same electron, but all positrons are also the same electron moving backward.

The one-electron universe postulate, proposed by John Wheeler in a telephone call to Richard Feynman in the spring of 1940, is the hypothesis that all electrons and positrons are actually manifestations of a single entity moving backwards and forwards in time.

Like so much of the quantum world, electrons are strange. What’s worse, they’re all strange in exactly the same way. Every electron is identical to every other electron. They all have the same mass, the same electric charge, and the same spin.

Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. The mass of an electron is almost 1,000 times smaller than the mass of a proton.
