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
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
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
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
