What wavelength of electromagnetic radiation carries the most energy?
Gamma rays have the most energy per photon.
How do you calculate the energy in joules of a photon of green light having a wavelength of 529 nm?
The energy of this photon is 3,7351.10e-19 joules.
Why is radiation with shortest wavelength the most powerful?
In our Universe, EM radiation can only come in discrete chunks called "photons." The energy of each individual photon depends on the frequency of the EM radiation. Frequency depends on wavelength (or vice-versa): the shorter the wavelength, the higher the frequency. Thus, short wavelength photons have more energy. That's just how our Universe operates, whether or not we like it.
Determine the energy and wavelength of a wave with a frequency of 3.6X 1016 hertz Would this be a wave of interest to nuclear medicine?
assuming the wave is electromagnetic... the energy of a single photon of that frequency is given by the formula E=hf where E= energy of the photon h=the Planck constant f= the frequency of the photon From this the energy of the photon is the Planck constant (6.63 x10-34) multiplied by the frequency 3.6x1016 Hz. E= 23.9x10-18 Joules. The wavelength of any wave is determined by the equation wave speed = frequency x wavelength. thus, the wavelength is the wave speed divided by the frequency. since all electromagnetic waves travel at the speed of light then... wavelength = 3x108 / 3.6x1016 wavelength = 0.83x10-8 = 8.3x10-9 metres. The electromagnetic radiation corresponding to this energy and wavelength is ultraviolet radiation and may be of interest to nuclear medicine.
What is the highest energy form of electromagnetic radiation?
Energy is equal to Planck's constant times the speed of light divided by the wavelength of the light. E=h*c / lambda. So the electromagnetic radiation with the largest wavelength will correspond to the lowest energy. Since radio waves have the largest wavelength (about 1,000m) they will have the lowest energy!
A photon has a wavelength 628 nm. Calculate the energy of the photon in joules?
The energy of the photon is 3,1631.e-19 joule.
Microwave ovens emit microwave energy with a wavelength of 12.0 cm What is the energy of exactly one photon of this microwave radiation?
A photon of this wavelength has an energy of about 10 ^ -5 eV.
How do you calculate photon wavelength with only the energy of the photons?
Photon Energy E=hf = hc/w thus wavelength w= hc/E or the wavelength is hc divided by the energy of the photon or w= .2 e-24 Joule meter/Photon Energy.
What wavelength of electromagnetic radiation carries the most energy?
Gamma rays have the most energy per photon.
How do you calculate the energy in joules of a photon of green light having a wavelength of 529 nm?
The energy of this photon is 3,7351.10e-19 joules.
How are the wavelength and energy of electromagnetic radiation related?
The energy of one photon is given by its frequency X planck's constant Its frequency is given by the speed of light divided by the wavelength.
How do you find energy when given wavelength?
The energy in each photon (quantum) of electromagnetic radiation is(h) x (c) / (wavelength)h = Planck's Konstantc = speed of light
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
After the absorption, the matter has added energy equal to 'hf' the energy of the absorbed photon.
Is this true or false the shorter the wavelength of electromagnetic radiation the more energy carried by the wave?
This is true. Each photon carries more energy when it has shorter wavelength / higher frequency.
What increases As the wavelength of electromagnetic radiation?
Remember that for any wave, wavelength x frequency = speed (of the wave). So, as the wavelength increases, the frequency decreases. Also, since the energy of a photon is proportional to the frequency, the energy will decrease as well in this case.
How do you find the energy of a photon?
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
The energy of a photon is related to its?
... frequency of the electromagnetic radiation of which the photon is a particle.
