How much energy does a 185 NM wave of light have?
The energy is 6.756 electron volts of energy, 1.25uevm/.185um = 6.756 ev.
Determine the energy of a single photon in a monochromatic beam of light of wavelength 625 nm?
1.99 eV
Which has a lower amount of energy red light or blue light?
red light
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
What is the ground state energy of the B4 plus ion i.e n equals 1 and the energy of the next four highest energy levels?
n = 1 = -340.8 eV n = 2 = - 85.00 eV n = 3 = - 37.78 eV n = 4 = - 21.25 eV n = 5 = - 13.60 eV
How much energy does Uv Light Visible Light and X-Rays have?
X-ray energies in the range 120 eV to 120 keV. UV energies from 3eV to 124 eV.
How much energy does a 185 NM wave of light have?
The energy is 6.756 electron volts of energy, 1.25uevm/.185um = 6.756 ev.
Determine the energy of a single photon in a monochromatic beam of light of wavelength 625 nm?
1.99 eV
What is the energy of a single photon at a wavelength of 9.3um in eV?
The energy is hc/w = 1.344E-1 ev
Why does blue light tend to produce the photo-electrons?
Blue light has sufficent energy to liberate electrons, E = hf=( 1ev/240Thz)f. Blue light is around 800 Thz and thus E = 800/240 ev=10/3 ev.
Which has a lower amount of energy red light or blue light?
red light
Why does red light use more energy than blue light?
no red uses more energy
What is higher energy red light or yellow visible light?
Red
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
What is the ground state energy of the B4 plus ion i.e n equals 1 and the energy of the next four highest energy levels?
n = 1 = -340.8 eV n = 2 = - 85.00 eV n = 3 = - 37.78 eV n = 4 = - 21.25 eV n = 5 = - 13.60 eV
Low-frequency red light is used in dark rooms because it does not expose the film. This is because the red light has a low?
Red light has low energy.
What is the energy of a photon emitted with a wavelength of 92.323 nm?
The energy is 2,5116.10-18 J or 13,429 eV.
