What is the relationship between wavelength and voltage?
The higher the accelerating voltage, the smaller the wavelength of the electrons and the higher the possible achievable resolution.
What is the wavelength of the electrons?
wavelength of an electron is calculated for a given energy (accelerating voltage) by using the de Broglie relation between the momentum p and the wavelength λ of an electron (λ＝h/p, h is Planck constant).
What is the relationship between a wave’s energy and its effect on matter?
In a transverse wave, the wave energy causes the matter to move up and down or back and forth at right angles to the direction the wave travels, however in a compressional wave, matter in the medium moves forward and backward in the same direction that the wave travels.
What is the de Broglie wavelength of an electron with a kinetic energy of 2 eV?
621 nm
Why de Broglie wavelength for an electron is longer than for neutron?
Answer: The de Broglie wavelength of a particle is inversely proportional to its momentum p = m v; since a proton is about 1800 times more massive than an electron, its momentum at the same speed is 1800 times that of an electron, and therefore its wavelength 1800 times smaller. The electron has the longer wavelength.
What will be the wavelength of electron of energy 100 eV?
we get λ=1.
What will be the de Broglie wavelength of an electron having kinetic energy of 500ev?
E = hc/λ or λ = hc/E = (6.626 x 10-34 Js)(2.99 x 108 m/s)/(8.1 x 10-17 J) λ = 2.44 x 10-9 m = 2.44 nm, which is about 5 times too big!
What is the wavelength of the wave associated with an electron having kinetic energy 100ev?
6×10−36m.
How does the intensity affect the photoelectric current?
In the photoelectric effect, light incident on the surface of a metal causes electrons to be ejected. 1, just the opposite behavior is observed in the photoelectric effect. The intensity affects the number of electrons, and the frequency affects the kinetic energy of the emitted electrons.
