The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer: 4) Einstein<\/strong><\/p>\n\n\n\n The photoelectric effect<\/strong> is the phenomenon where electrons are ejected from the surface of a material<\/strong> (usually a metal) when it is exposed to light of a certain frequency<\/strong>. While this effect had been observed in experiments, classical physics could not explain why light below a certain frequency, no matter how intense, failed to eject electrons.<\/p>\n\n\n\n The first person to successfully explain the photoelectric effect was Albert Einstein<\/strong> in 1905<\/strong>. Einstein proposed a revolutionary idea<\/strong> that built on Max Planck\u2019s quantum theory<\/strong>, which had introduced the concept of energy quantization to explain blackbody radiation.<\/p>\n\n\n\n Einstein suggested that light is made up of discrete packets of energy<\/strong>, which he called photons<\/strong>. According to his theory, each photon has energy E = hf<\/strong>, where h<\/em> is Planck\u2019s constant and f<\/em> is the frequency of the light. When a photon strikes an electron in a metal, if the photon’s energy is greater than the work function<\/strong> (the minimum energy needed to release the electron), the electron is ejected. Any extra energy becomes the kinetic energy of the ejected electron.<\/p>\n\n\n\n This explanation solved the mystery that classical wave theory could not:<\/p>\n\n\n\n Einstein\u2019s explanation was later confirmed by experiments and became a cornerstone of quantum mechanics<\/strong>. In 1921<\/strong>, he was awarded the Nobel Prize in Physics<\/strong> specifically for his work on the photoelectric effect\u2014not for his theory of relativity, as many believe.<\/p>\n\n\n\n In summary, Albert Einstein<\/strong> was the first to successfully explain the photoelectric effect by proposing the quantum nature of light, fundamentally changing our understanding of physics.<\/p>\n","protected":false},"excerpt":{"rendered":" Who was the first to successfully explain the photoelectric effect? options: 1) Planck 2) Young 3) Bohr 4) Einstein 5) Heisenberg The correct answer and explanation is: Correct Answer: 4) Einstein Explanation (300 words): The photoelectric effect is the phenomenon where electrons are ejected from the surface of a material (usually a metal) when it […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-21371","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21371","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=21371"}],"version-history":[{"count":2,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21371\/revisions"}],"predecessor-version":[{"id":21373,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21371\/revisions\/21373"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=21371"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=21371"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=21371"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
