An electron in a hydrogen atom could undergo any of the transitions listed below, by emitting light. which transition would give light of the shortest wavelength? hint: think planck, remember bohr. you may also want to think about the rydberg equation, but it is not necessary to do the calculations.

option 4. Transition of n=4 to n= 1

Explanation:

An electron in an atom could undergoing any transitions the greater the n value, the higher the energy of the electron.

Therefore, the difference between the initial n values and

the final n values is equal to energy of the emitted photon. That is;

n(1)- n(2)= photons' energy (1).

Worthy of note is the fact that the energy of the photon is inversely proportional to the wavelength of

the emitted radiation.

Therefore, the farthest electron will have the shortest wavelength. That is n=4 to n=1

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

3. dark matter

empty space could also be a simple vacuum
