Question 2

In an analysis relating Bohr's theory to the de Broglie wavelength of electrons, when an electron moves from the n = 1 level to the n = 3 level, the circumference for its orbit becomes 9 times greater. This occurs because:
a. the wavelength of the electron becomes nine times as long.
b. there are triple as many wavelengths, and each wavelength is triple in length.
c. there are nine times as many wavelengths in the new orbit.
d. the electron is moving nine times as fast.
