WebPhotoelectrons can be ejected from the metal surface only when the incident radiation has a shorter wavelength than the cut-off wavelength. The work function of silver is ϕ = 4.73 eV ϕ = 4.73 eV . To make the estimate, we use Equation 6.16. Solution The threshold wavelength for observing the photoelectric effect in silver is WebThe linear mass density decreases. If L remains ﬁxed, then the combined eﬀects of increased tension and decreased linear mass density results in the wave velocity increasing, which, for a given driving frequency, means a longer resulting wavelength. In any case, resonance requires higher fre-quencies than it otherwise would. 6. uk forward
