Here v 0 is the photoelectric threshold frequency of the electromagnetic light rays, w is the work function of the metal. Therefore, ϕ = h ν 0. Web find the threshold wavelength. The metal's threshold wavelength is a wavelength of light. You can rearrange this formula to. It is measured with units of length (typically nm if referring to the visible light portion of the. Above this frequency, the kinetic energy of the emitted. Web 514k views 5 years ago new ap & general chemistry video playlist this chemistry video tutorial explains how the photoelectric effect works. Work function can be obtained by: So yes, you would use a chart converting wavelengths of light to the color to identify it.
When the work function is large (when electrons are bound fast to the metal surface), the energy of the threshold photon must be large to produce a. Web learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. Hard solution verified by toppr w= λnc λ threshold= whc λ threshold= 1.151240 λ threshold=576.8m was this answer helpful? Web explanation of solution given data: Web the formula to calculate the wavelength of a wave is: Work function can be obtained by: Web = 0.814 m/s exercise : Khan academy is a nonprofit with the. Web hence after a certain minimum frequency of incident light, the electrons start emitted from a metal surface. So yes, you would use a chart converting wavelengths of light to the color to identify it. The metal's threshold wavelength is a wavelength of light.
