Albert Einstein is probably the most famous physicist of all time. He is best known for his studies involving the
When an electromagnetic radiation (light) is hitting on a material and if the energy ( or frequency ) of the light is more the the a certain value then electrons are emitted from this material this phenomenon known as photoelectric effect and the minimum energy required is known as work fuction of the materials and it is a constant for a particular material and the corresponding frequency or wavelength is called cut off frequency or wavelength.
