4. What is the Photoelectric Effect?
Photoelectric effect is a phenomenon that discusses the striking of photons of light on the metallic surface. When photons hit a metal surface, there is an emission of photoelectrons. However, the number of photons hitting the metal will not eject the same number of electrons.
5. What is the dual nature of radiation and matter?
Light and other similar electromagnetic radiations possess dual nature. This implies that they have both the particle nature as well as the wave nature. Previously properties of such radiation and matter used to be explained only through the particle nature. However, later it was concluded experimentally that radiation and matter also have wave properties. Therefore, matter such as light is considered to have dual nature, that is, both the properties of a wave and a particle.
6. What is the dual nature of matter notes?
The dual nature of matter makes up a crucial concept for the syllabus of physics in competitive exams such as JEE and is essentially the understanding of the double nature that matter has or exhibits. A given matter usually displays or has either the particle nature of the wave nature. Several experiments have been conducted further so as to prove this hypothesis. You can find notes related to this at Vedantu at free of cost.
7. What is Heisenberg’s Uncertainty Principle?
Heisenberg’s Uncertainty Principle stipulates that the momentum as well as position of a particle is not possible to be derived simultaneously.
Mathematically, this is expressed as follows:
∆x ∆P ≥ (h / 4π)
Here, ∆x stands for Uncertainty in position.
And, ∆P stands for the Uncertainty in Momentum.
