Wavelength of an electron

Self-Test 1.6A Calculate the wavelength of an electron traveling at 1/1000 the speed of light (see the inside back cover of this book for the mass of an electron). [Pg.138]

The second view is based on the uncertainty relation between coordinate and momentum. In the region of a classically allowed barrier, the de Broglie wavelength of an electron is... [Pg.64]

The de Broglie concept of wave-particle duality enables us to calculate the wavelength of an electron. According to the de Broglie equation,... [Pg.440]

Self-Test 1.5A Calculate the wavelength of an electron traveling at 1/1000 the speed of light. [Pg.157]

The smaller wave in microscopy is achieved by the use of electrons instead of visible light. The wavelength of an electron beam is extremely small. Thus, objects like bacteria and viruses can be visualized. Indeed, versions of microscopes that rely on electrical repulsion between surfaces can now visualize molecules, including the constituents of deoxyribonucleic acid (DNA). [Pg.334]

SAMPLE PROBLEM 7.3 Calculating the de Broglie Wavelength of an Electron... [Pg.219]

Problem Find the de Broglie wavelength of an electron with a speed of 1.00X10 m/s (electron mass = 9.11X10 kg h = 6.626X kg-m /s). [Pg.219]

How does the waveiength of a fast-pitched baseball compare to the wavelength of an electron traveling at 1/10 the speed of light What is the significance of this comparison See Example 7.3. The Bohr model only works for one electron species. Why do we discuss it in this text (what s good about it) ... [Pg.330]

The wavelength of an electron in an electron microscope is 0.0122 nm. What is the electron velocity ... [Pg.21]

Calculate the de Broglie wavelength of an electron moving at l/137th the speed of light. (At this speed, the relativistic correction to the mass is negligible.)... [Pg.19]

In the subject of quantum mechanics, particles such as electrons and protons can be described in terms of their wave nature. The lighter the particle the larger is its wavelength, and the wavelength of an electron can be... [Pg.224]

The wavelength of an electron is larger than its radius, while the wavelength of the baseball is insignificant compared with the size of the ball. Therefore, the wavelike nature of matter is only important for extremely small objects, such as atoms, nucleons, and electrons. [Pg.59]
