According to parallelogram law of vector addition :
Work done by each is the same for they reach the same height. The one who climbs in 30s uses more power because work is done in a shorter time.
Answer:
(507 nm)
Explanation:
First of all let's calculate the energy of the photon absorbed by the electron, This is given by
where
h is the Planck constant
is the frequency of the photon
Substituting,
The energy of the second photon, the one emitted when the electron drops to the intermediate energy level, is 2/3 of this energy:
The relationship between the energy of the photon and its wavelength is
where c is the speed of light. Solving for , we find the wavelength:
Answer:
