Properties of electromagnetic waves

Electromagnetic (EM) radiation is a form of energy that surrounds us and takes many forms such as radio waves, microwave, X-ray and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small part of the EM spectrum and contains a wide range of electromagnetic wavelengths. Electricity and magnetism […]

The photoelectric effect occurs when a material absorbs electromagnetic radiation and emits electrically charged particles from or within it. The phenomena of a substance (metal) emitting electrons when subjected to suitable frequencies of radiation is known as the photoelectric effect, and the produced electrons are known as photoelectrons. Photons A photon, often known as a quantum,

Einstein explained the photoelectric effect using Planck’s formula. According to Planck’s formula, the light was a beam that had several particles. In this article, we will understand how Einstein explained the photoelectric effect and why earlier scientists failed to do this. Why Did Scientists before Einstein Fail to Explain the Photoelectric Effect? This concept came

The Compton effect describes the increase in wavelength of photons (X-rays or gamma rays) as a result of scattering by a charged particle (usually an electron). The effect has become one of the cornerstones of quantum mechanics, which describes both the wave and particle aspects of radiation. By treating X-rays as discrete heartbeats, or quanta,
