(a) If the wavelength of an electron is 5.12 ✕ 10−7 m, how fast is it moving? km/s (b) If the electron has a speed equal to 3.90 ✕ 106 m/s, what is its wavelength? m
1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g. Top speed for a professional pitcher is about 100 mph when he throws a fast ball. Find...
Calculate (in nm) the de Broglie wavelength for each of the following. (a) an electron with a velocity 17% of the speed of light ______nm (b)a tennis ball (56 g) served at 44 m/s (~98 mi/h) ______nm
If the De Broglie wavelength of an electron is equal to 400 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. Answer: 1832.42 m/s If the kinetic energy of an electron is 400 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron. I cannot figure out the second part, please explain!
