Question

Look for an article or news story/video that relates to one or more of the following topics:

• Special relativity
• Photons
• Photoelectric effect
• Quantum mechanics

Write a 250 word post about the article relative to one of the topics above and cite it. Include how it applies to everyday life

Answer 1

Photons

When we hear the word photon what first comes in mind is that it is a type of elementary particle which is a basic unit of all light and its true, although it also shows wave properties. Photon in general shows wave particle duality. This particle always remain in motion with the speed of light. they have zero mass and rest energy,no charge and spin 1 particle and they obey bose einstein statistics. this is the type of a particle that can be created and destroyed. since it is basic unit of light the biggest source of photon on our earth is our sun, the light from the sun came in the form of photons and these photons help us to see the world what it really is they are also absorbed by our body wherever there is light or it is produced. the study of the photon let scientist work on many different different aspects some of them are black body radiation, wave particle duality, photoelectric effect. In physics it is generally denoted by the symbol γ (gamma). it is interesting to knoe that the  antiparticle of the photon is photon himself the energy of photon is given by E=hν where h is plancks constant and ν (nu) is photon frequency. these are some facts that are related to photon and they are all normal photons are like everywhere in our surrounding and in our universe. In the begining of time when the universe was created there is time referred as a photon epoch at that time the the photons dominated the energy of the universe. photons interact via elecromagnetic and weak interactions. there are so many of things about photons and the involvement of photons in natural processes as some of them are discussed earlier everthing in a way is related to one way or other to the photons .
