The discussion revolves around the photoelectric effect, specifically comparing the effects of blue light (450 nm) and yellow light (560 nm) on a metal surface. Participants are exploring how the wavelength of light influences the number of electrons emitted and their kinetic energy.
The conversation is actively exploring the implications of energy delivery and photon count on electron emission. Some participants have provided insights regarding the relationship between wavelength and photon generation, suggesting that longer wavelengths may lead to more photons for the same energy input.
There is an underlying assumption that the same amount of energy is delivered by both lasers, which is being critically examined in relation to the number of emitted electrons.
A photoelectric experiment was performed by separately shining a laser at 450 nm (blue light) and a laser at 560 nm (yellow light) on a clean metal surface. Both wavelengths are above the theshold wavelength for the metal, and the same amount of energy is delivered to the metal surface by each laser.
Which laser would shed more electrons, and which laser would shed electrons with the most kinetic energy?
The number of electrons depends on the number of photonsJules18 said:I thought the # of e- only depended on the intensity of the light
Yes, how is energy related to number of photons?and the question says the same amt. of energy was delivered by each laser.
