Answer to Problem 32P

The de Broglie wavelength of the electron is 5.79×1010m .

Explanation of Solution

The equation for de Broglie wavelength of the electron in terms of kinetic energy is,

λe=h2me(KE)

    • h is the Plank’s constant
    • me is the mass of the electron
    • KE is the kinetic energy

Substitute 6.63×1034J.s for h , 9.11×1031kg for me and 4.50eV for KE .

λe=6.63×1034J.s2(9.11×1031kg)(4.50eV)(1.60×1019J1eV)=5.79×1010m

Conclusion:

Thus, the de Broglie wavelength of the electron is 5.79×1010m .

Answer to Problem 32P

The de Broglie wavelength of the bowling ball is 2.26×1025m .

Explanation of Solution

The equation for de Broglie wavelength of the bowling ball in terms of kinetic energy is,

λb=h2mb(KE)

    • mb is the mass of the bowling ball

Substitute 6.63×1034J.s for h , 6.00kg for mb and 4.50eV for KE .

λb=6.63×1034J.s2(6.00kg)(4.50eV)(1.60×1019J1eV)=2.26×1025m

Conclusion:

Thus, the de Broglie wavelength of the bowling ball is 2.26×1025m .

Answer to Problem 32P

The de Broglie wavelength of the photon is 2.76×107m .

Explanation of Solution

The equation for de Broglie wavelength of the photon is,

λp=hcE

    • c is the speed of light
    • E is the energy of the photon

Substitute 6.63×1034J.s for h , 3.00×108m/s for c and 4.50eV for E .

λp=(6.63×1034J.s)(3.00×108m/s)(4.50eV)(1.60×1019J1eV)=2.76×107m

Conclusion:

Thus, the de Broglie wavelength of the photon is 2.76×107m
