Hello friends, i have a big trouble because i am not able to understand what is meant by particle nature and what is meant by wave nature. I need to know what kind of behavior we classify it as wave nature and which behavior we classify as it to be particle nature? Once you have explained it to me,difference in behavior of wave nature and particle nature,explain me what should be the experimental results if radiation were to act like a wave and then as a particle. Obviously,the behavior would be of particle nature and as result Quantum Theory came in!!! Well,i will tell you how much i know about black-body radiation and all its experiment. An Ideal Body which absorbs and emits all frequencies of radiation is called a black-body and it's emitted radiation is called black-body radiation. While observing a graph which has intensity at one axis and wavelength at the other,at a constant temperature,it is observed that intensity of the emitted radiation is greater as wavelength decreases,reaches a maximum value for a specific wavelength and intensity of radiation decreases with further decrease in wavelength. I think according to wave nature of electromagnetic theory, i think( i am not sure,just a guess) as the temperature of black-body increases,frequency of emitted radiation increases but intensity of the radiation should be same as the intensity of the radiation through which we made the black-body to absorb. But the result is that intensity is the function of wavelength at the constant temperature. So how is this can be explained with particle nature? I think this is what helps to distinguish particle nature with wave nature.
