About Chapter Dual Nature Of Matter & Radiation👇

This Chapter is Devided into 2 Parts. First Part is Particle Nature of Radiation & 2^nd part is Wave Nature of Matter. In Particle Nature of Matter you will study Photoelectric effect. Photoelectric Effect is ejection of electrons when light of suitable frequency falls on metal Surface.

Threshold Frequency– Minimum Frequency which is Capable for Ejection of electrons.

Work Function– Minimum Amount of Energy Required for ejection of electrons.

Stopping Potential- Minimum Retarding Potential which is capable to stop Photoelectrons.

Helpfull Conversion for this Chapter

1 eV = 1.6 × 10^-19 J

1eV is Amount of work done to move an electron through a potential Difference of 1 Volt. It is unit of Energy.

In Wave Nature Of Matter

Debroglie gave a bold Hypothesis that Matter should posses dual Nature. He gave this Hypothesis because

• Whole energy in this Universe is in the form of Matter & Electromagnetic Radiation. Nature Loves Symmetry as radiation has got dual nature matter should also possess dual nature.
