2.96 x 10^-19 J
What is the energy of a photon that emits a light frequency of 7.21 x 1014 Hz?
4.78 x 10-19
What is the energy of a photon?
the energy of a photon is h times f
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.

What is the difference between linear and non linear optics?
In the case of linear optical transitions, an electron absorbs a photon from the incoming light and makes a transition to the next higher unoccupied allowed state. When this electron relaxes it emits a photon of frequency less than or equal to the frequency of the incident light (Figure 1.3a). SHG on the other hand is a two-photon process where this excited electron absorbs another photon of same frequency and makes a transition to reach another allowed state at higher energy. This electron when falling back to its original 39 state emits a photon of a frequency which is two times that of the incident light (Figure 1.3b). This results in the frequency doubling in the output.

What is the process in which an electron returns to a lower energy level and emits a photon?
line emission
What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
When electron drops to a lower energy level what is the energy of the proton released?
You may be confusing "proton" with "photon". A proton is a positively-charged particle contained within the nucleus of an atom. A photon is a discrete unit of energy normally expressed as light. Around the nucleus of the atom, there are some electrons in energy levels. When an atom absorbs energy, it absorbs a specific amount, or "quantum" of energy and the electron boosted to a higher energy level. When the electron drops to a lower energy level, it emits a photon in the form of light at a specific energy and frequency.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
What is the energy of a photon the emits a light of frequency 4.47 x Hz?
The energy of a photon when frequency is known is E = hv, where E is energy in Joules, h is Planck's constant, 6.626 x 10-34 Joule•second, and v is frequency.E = 6.626 x 10-34 J•s x 4.47 x 1014 Hz = 2.96 x 10-19 Joules
