WebIt has been shown that two equal series of waves, proceeding from centres near each other, may be seen to destroy each other's effects at certain points, and at other points to redouble them; and the beating of two sounds has been explained from a similar interference. WebSay in a photoelectric experiment, we find a stopping potential of 1.85V for λ = 3000 A ∘ and of 0.82V for λ = 4000 A ∘. How can I get the Planck's constant from the above … great west produce company

WebPredictions based on light as a wave. To explain the photoelectric effect, 19th-century physicists theorized that the oscillating electric field of the incoming light wave was heating the electrons and causing them to vibrate, eventually freeing them from the metal surface.

Thomson (Figure 1.3.1 ). Figure 1.3.1 : The photoelectric effect involves irradiating a metal surface with photons of sufficiently high energy to cause the electrons to be ejected from the metal. great west produce
