Question

If the speed of an electron increases, what is true about its wavelength? The wavelength increases An electron doesn't have a wavelength The wavelength decreases The wavelength stays the same What happens to the energy of an electron inside a long molecule as the electron's wavelength decreases? An electron doesn't have a wavelength The energy decreases The energy increases The energy stays the same Given the quantized energy levels of a molecular system (a quantum harmonic oscillator, or a quantum string), which transition of the molecule will emit a photon with the longest wavelength? A transition from the first excited state to the ground state A transition from the second excited state to the ground state A transition from the ground state to the second excited state A transition from the ground state to the first excited state

Explanation / Answer

1)The wavelenghth decreases

when speed of electron increases the specific charger decreases because with increase in velocity charge remains constant. Another reason is specifice charge is the ratio of the charge to mass.

2)

The energy increases

if the wavelength increase the energy will decreases due to: E=hfE=hf.

But actually the energy of electron increases if energy level increases!!

3)A Transition from the first excited level to the ground level
