Question

What is a blackbody? How does its peak wavelength depend on temperature? What is a photon, and how does its energy depend on wavelength? On frequency? What is the photoelectric effect, and how do you calculate the maximum kinetic energy of released electrons? How do you use voltage to calculate the minimum wavelength of produced X-rays? How do you calculate wavelength change in the Compton effect? Energy change? How do you calculate the wavelength of a particle or photon given its momentum? What is Heisenberg's uncertainty principle?

Explanation / Answer

* blackbody can be any body which doesn't escape light of it,means any light fallin on a black body got absorbed by the body itself.

*photon is a energy unit carries by light.

*e=hv (h=planks constant)(v=frequency)(e=energy)

*e=hc/ (c=velocity of light)(=wavelength of light)

so energy is directly proportional to frequency and inversely proprtional to wave length)

* maximmum K.E of electron=mv2/2 (m=mass of electron)(velocity of released electron)
