The wave nature of the particle can be explained by the de broglie equation which relates the wavelength, mass and the speed of the particles. The de broglie equation can be expressed as follows: hmv=λ where h = plank's constant m = mass v = ...
b) What is the wavelength of the wave generated? Homework Equations The equations are the problems that I am stuck on, I do not know the equations any more and would be very grateful if somebody could jog my memory. :) The Attempt at a Solution I do remember an equation ...
b. What is the wavelength of a photon of energy 10.2 eV? For an electron with a de Broglie wavelength of 2.5 nm, what is the kinetic energy (in eV)? What is the de Broglie wavelength of a 5.0-eV electron? What is the de Broglie wavelength of a 3.0...
The period of a wave, T (s), is the time for one cycle of the wave to pass a given point. If the speed at which the wave travels is v (m/s), then these three parameters are related by the following simple equation of motion: ...
Wavelength: The length of a complete wave, i.e., the distance between two consecutive particles having the same phase at an instant, is called the wavelength (λ). In Fig., OD and AE is the wavelength of the transverse wave. Again in Fig., CE and DF is the wavelength of the longitu...
Wavelength formula Divide the velocity of a wave by its frequency to calculate wavelength. This is often expressed as the equation seen here. The Greek letter lambdaλrepresents wavelength, expressed in meters. Thevis wave velocity, calculated as meters per second (m/s). And thefstands for fre...
Homework Statement The time plot for a wave of wavelength 0.68 m, moving toward the right, is shown at x = 1.2 m in the figure below. (Assume the wave is...

An electron has a de Broglie wavelength equal to the diameter of a hydrogen atom in its ground state. (a) What is the kinetic energy of the electron? (b) How does this energy compare with the magnitude of the ground - state energy of the hydrogen atom ...
λ = wavelength Wave Formula Derivation The derivation of the wave equation certainly varies depending on context. There is a particular simple physical setting for the derivation. Moreover, this setting is that of small oscillations on a piece of string in accordance with theHooke’s law. ...
