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...

Question 5 Calculate the wavelength of the following subjects using de Broglie equation. (1) A baseball of 145 g and moving at a speed of 45 m/s (about 100 miles per hour) (2) An electron moving at a speed of 1.2 x 107 m/s (3) Which one of the above is likely to behave like a wave, such as interference and diffraction?
A) If the De Broglie wavelength of an electron is equal to 350 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. B) If the kinetic energy of an electron is 440 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.
