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. This video is highly rated by Class 11 … Matter waves- wave nature of particles, de Broglie relation. Wavelength and frequency of a wave are inversely proportional. These rays are produced in a discharge tube at a pressure below 0.01 rom of mercury. Davisson-Germer experiment (experimental details should be omitted; only conclusion should be explained). Its wave nature is represented by its velocity, frequency and wavelength. There is no charge on X-ray thus these are not deflected by the electric field and magnetic field. It is represented by ‘T’ and measured in seconds. Dual Nature of Matter and Radiation is one of the most important chapters from modern physics while preparing for all competitive exam because it helps you to understand the dual nature of matter. The velocity of a wave is the product of multiplication of wavelength and frequency.

Electromagnetic radiations travel in space and vacuum through oscillating electrical and magnetic fields generated by their particles. All we can say is that wave-particle duality exists in nature: Under some experimental conditions, a particle appears to act as a particle, and under different experimental conditions, a particle appears to act a wave. These oscillating electrical and magnetic fields are perpendicular to each other and to the direction of propagation of the wave. Offer ending soon! 0 Essay(s) Pending (Possible Point(s): 0).
