Answer:
∝= 51.08 nm
Explanation:
It is necessary that the photon have the enough energy to get out of the ground state and the energy required to jump out of the ground state = 13.6 eV
so we have the total energy needed:
E= 13.6+10.7
E= 24.3 eV
Planck constant = 6.62*10^-34
with the E formula we could clear the wavelength variable like this....
E= hf
E= h(c/∝)
∝= h*(c/E)
∝=(6.62*10^-34) * [ 3*10^8 / 24.3*(1.6*10^-19)J ]
∝= 5.108*10^-8m
now we just need to convert to a nm distance
∝= 51.08 nm
It is the time period where the commonly accepted theory of the earth being at the center of the solar system is switching over to the refused theory of the sun being at the center of the solar system.
Answer: Kinect Energy
Explanation: As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy. ... In doing so, you have increased the potential energy of the book (by increasing its potential to fall down to the floor).
