some Question and answers in em waves



can you ist five examples of electromagnetic radiation
Example of electromagnetic waves are radiowaves, light waves, x-rays,  and thermal radiations.
which part of the electromagnetic spectrum has the highest energy
associated with it
Electromagnetic radiations with the highest frequency is also the wave with the highest energy , the wave is the gamma ray  with frequency ranging from above 3 x 1019hzt.  And energy over  105ev.
list the regions of the electromagnetic spectrum in order of
increasing energy
Electromagnetic waves are classified based on either their frequency or wavelength as revealed by the wave equations
V= fλ, where v is the velocity of the wave, f is the frequency and λ is the wavelength. Wavelength and frequency varies inversely , em waves with highest frequency have lowest wavelength and viceversa.
what kind of electromagnetic radiation has the longest wavelength
 the major regions of em waves in order of increasing  frequency  are
1.     Radiowaves
2.     Microwaves
3.     Infrared
4.     Visible light
5.     Ultraviolet
6.     X-ray
7.     And gamma ray
The energy equation  e=hf,  shows the energy of wave is proportional to the frequency , therefore the above is in order of increasing energy.
what are the three quantities that can express the electromagnetic spectrum
 the three properties at can expresses em waves  spectrum are the wavelength , frequency and energy , the electromagnetic waves are classified based on te variations of the above otherwise all other properties are same. The following equation can explain it further, e= hf = hc/λ. Where e is the energy, h plank constant, f frequency, c speed of waves, and λ wavelength.  The energy varies proportionally with increasing  frequency but decreases with increasing wavelength.
which em wave has the highest energy associated with it
 the electromagnetic wave with the highest energy is the gamma ray because it has the highest frequency and frequency is proportional to energy as given by equation e =hf.
what kind of electromagnetic radiation has the longest wavelength
The electromagnetic wave with the longest wavelength is the radiowaves because of its lowest frequency. And wavelength is the inverse of frequency λ= 1/f
 which region of the electromagnetic spectrum has the highest energy
The wave with the highest energy is the gamma ray because  energy is proportional to wave frequency e =hf.
what are the the highest energy waves in the electromagnetic spectrum
The  part with highest in em spectrum is the gamma .
which part of the electromagnetic spectrum has the lowest frequency
The part with the lowest frequency is is the part with the longest wavelength which is radiowaves.
explain what happens when the electron moves from the first energy level
to the second energy level
According to bohr atomic model when an electron in an atom, is excited it jump from it ground state to a higher energy level .
 when an electron in its ground state absorb energy, the excited  electron can jump from its ground state  to a higher energy level and will release em wave  when it return back to its original energy state, the energy (em wave ) it will release is proportional to the difference between the two energy levels
