The wavelength of the ball with mass of
Concept Introduction:
de Broglie established a relation for particles of matter that they also can behave as a wave and has a wavelength. The wavelength of the particle is inversely related to its mass. The smaller the mass, the larger will be its wavelength.
The expression given by the de Broglie is as follows:
Here,

- Show that the value of the Rydberg constant per photon, 2.179 1018 J, is equivalent to 1312 kJ/mol photons.arrow_forwardWhat is the de Broglie wavelength of a 149-g baseball traveling at 23.0 m/s (51.4 mph)? Is the wavelength much smaller or much larger than the diameter of an atom (on the order of 100 pm)?arrow_forwardA baseball weighs 142 g. A professional pitcher throws a fast ball at a speed of 100 mph and a curve ball at 80 mph. What wavelengths are associated with the motions of the baseball? If the uncertainty in the position of the ball is 12 wavelength, which ball (fast ball or curve) has a more precisely known position? Can the uncertainty in the position of a curve ball be used to explain why batters frequently miss it?arrow_forward
- An FM radio station found at 103.1 on the FM dial broadcasts at a frequency of 1.031188s1 (103.1 MHz). What is the wavelength of these radio waves in meters?arrow_forwardWhen the Sojourner spacecraft landed on Mars in 1997, the planet was approximately 7.8 107 km from Earth. How long did it take for the television picture signal to reach Earth from Mars?arrow_forwardWhat is the wavelength of a proton traveling at a speed of 6.21 km/s? What would be the region of the spectrum for electromagnetic radiation of this wavelength?arrow_forward
