Question

Explain:

i.Dual behavior of matter

ii.Heisenbery’s uncertainity principal

iii.Photo electric effect​

Answer 1

Answer:

1) Dual nature of matter is an important concept in JEE physics and is basically the study of different nature that a matter possesses or exhibits. Hence, the matter is said to possess dual nature, i.e., it has both the properties of a particle and as well as a wave.

2)At the foundation of quantum mechanics is the Heisenberg uncertainty principle. Simply put, the principle states that there is a fundamental limit to what one can know about a quantum system. For example, the more precisely one knows a particle's position, the less one can know about its momentum, and vice versa.

Answer 2

Answer:

1. Dual nature of matter is an important concept in JEE physics and is basically the study of different nature that a matter possesses or exhibits. Hence, the matter is said to possess dual nature, i.e., it has both the properties of a particle and as well as a wave.

2. Heisenberg uncertainty principle states that for particles exhibiting both particle and wave nature, it will not be possible to accurately determine both the position and velocity at the same time. The principle is named after German physicist, Werner Heisenberg who proposed the uncertainty principle in the year 1927.

3. photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.
