Wave and Photons

This week we will be going back to basics to explain the fundamentals of modern day physics and in turn it becomes the fundamentals of quantum mechanics.
Photons are like particles but are much smaller atoms. The more light a light source gives off the more photons are being shoot off. Light is a form of energy that behaves like a radio wave and in turn has its own wavelength,
For those of you who do not know what a wavelength is it is the distance between the top a one wave and the next wave.
A lights colour depends on its wavelength. The colour purple has the shortest wavelength with red having the longest wavelength. photos with a wavelength of less than 400nm (nanometre) or more than 700nm it is invisible to the human eye.
The shorter the wavelength of the photon the more energy it carries for example an ultraviolet carries more energy than an infra-red photon.
Wavelength and frequency are inversely proportional so we one increases the other one decreases and vice versa. Humans can detect photons that are invisible to the human eye though heat, for example we can feel the heat from a warm brick after it has been heated up from the sun without actually seeing the photons that are warming it up as the energy each photon releases is converted to heat energy.
Quantum mechanics started when  it was discovered that certain frequency means a certain amount of energy. So in turn energy is proportional to frequency. The higher frequency a photon has the more energy it carries. This can be used to calculate how much damage it can do.
