Calculation QM 2 (qm-02)

Electrons from the solar wind arrive after a flight time from something 30 H to Earth, where they can generate polar lights.
In the case of polar lamps, green light rays are predominant, which, by stimulating the λ = 557.7 Nm They will be called.
Calculate that the kinetic energy of the electrons of the solar wind is sufficient to stimulate oxygen.
Note: The distance between the Earth and the Sun is equal to 150 The Commission's proposal km
Notes 2: m(e^–)= 9.1·10^-31 kg
