Question

what is the de broglie wavelength in nanometers associated with a 2.5 gram ping pong ball traveling 35 miles per hour?

Answer #1

If a 3.5 gram ping pong ball were traveling to the right
horizontally at 12 m/s, and a larger 12 g super ball were thrown
directly behind it (also to the right) at 15 m/s so that the super
ball bumped into and elastically collided with the ping pong ball,
what would be the velocities of the two balls after the
collision?

PART A: What is the de Broglie wavelength of an electron
accelerated through 750 V ? Express your answer in nanometers.
PART B: What is the de Broglie wavelength of a proton
accelerated through the same potential difference?
Express your answer in nanometers.

Calculate the De Broglie wavelength of a bucky-ball, a
spherical molecule with molecular formula of
C60, traveling at a
velocity of 25.0 m/s. The molar mass of
C60 is 720.66 g/mol.

What is the de Broglie wavelength of the wave associated with an
electron that has been accelerated from rest through a potential of
50.0 V? Compare your answer to the typical distance between atoms
in a solid crystal, about10−10 ?. Would you expect diffraction to
occur as these electrons pass between such atoms?

accelerated through an electrical potential difference of 20 volts?
b) What is the de Broglie wavelength of a proton that is
accelerated through an electrical potential difference of 20
volts?

electron?

Compare the de Broglie wavelength of a 0.015-kg ball moving at
40 m/s to that of an electron which has a speed of
0.0073c. Given: mass of electron = 9.11 x
10-31kg, speed of light = c = 3 x 108
m/s.
