When is an electron in an atom likely to move from one energy level to another
diamong [38]
<h2>Answer:When electrons absorb or emit quantized units of energy in the form of photons.</h2>

Explanation:

When a electron is collided with a photon with exactly the same energy it would require to get to any of the farther orbits,electron transition takes place to an orbit depending on the energy of the photon.

When electrons emit exactly the same amount energy that is difference between the current energy level and the new level,then the electron makes a transition to the new level.

A friend of yours is loudly singing a single note at 412 Hz while racing toward you at 23.0 m/s on a day when the speed of sound

Doppler Effect is required to solve the problem. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other. The general formula of observed frequency, due to Doppler's effect is as follows,

f_0 = (\frac{v+v_0}{v-v_s})f_s

f_0 = Frequency observed by observer

v = Velocity of Sound

v_0 = Velocity of observer

v_s = Velocity of source

f_s = Frequency of source

PART A) Replacing our values we have that,

f_0 = (\frac{v+v_0}{v-v_s})f_s

f_0 = (\frac{344+0}{344-23})(412)

f_0 = 441.52Hz

PART B) Here the same procedure is performed but this time repeated in the opposite direction.

f_0 = (\frac{v+v_0}{v-v_s})f_s

f_0 = (\frac{344+23}{344-0})(420)

f_0 = 448.08Hz
