How much energy does ultraviolet light have?
Ultraviolet light has higher energy than visible light but lower energy than X-rays. The energy of ultraviolet light ranges from about 3 eV to 124 eV, depending on the specific wavelength.
What is the photon energy of red light having wavelength 640 nm?
The photon energy of red light with a wavelength of 640 nm is approximately 1.94 eV (electron volts). This can be calculated using the formula E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the light.
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
Which has a lower amount of energy red light or blue light?
Red light has a lower amount of energy than blue light. This is because red light has a longer wavelength, which corresponds to lower energy photons, while blue light has a shorter wavelength and higher energy photons.
How much energy does ulraviolet have?
Ultraviolet (UV) light has higher energy than visible light but lower energy than X-rays. It ranges from about 3 electron volts (eV) to 124 eV, with shorter wavelengths corresponding to higher energies. UV light is important for processes like photosynthesis and can cause skin damage if exposure is prolonged.
How much energy does ultraviolet light have?
Ultraviolet light has higher energy than visible light but lower energy than X-rays. The energy of ultraviolet light ranges from about 3 eV to 124 eV, depending on the specific wavelength.
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.

UV light is important for processes like photosynthesis and can cause skin damage if exposure is prolonged.
Do yellow light or red light have lower energy?
Red light has lower energy than yellow light. The energy of a light wave is directly proportional to its frequency, with red light having a lower frequency and therefore lower energy compared to yellow light.
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.
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 red light use more energy than blue light?
no red uses more energy
What is the energy of a single photon at a wavelength of 5nm in eV?
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values, the energy of a single photon at a wavelength of 5nm is approximately 2.48 eV.
Does UV or red light have more energy?
UV light has higher frequency, so it has more energy than red light has
