What is the wavelenght of red light?
it is short wavelength
What is the wavelenght of white light?
400 to 700 nm because white light is the mixture of all 7 coloured lights.
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.
What is the wavelength of a photon that has three times as much energy as that of a photon whose wavelength is 779 nm?
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
The energy of a 200 nm photon in eV is?
3.5 I am positive
What is the wavelenght of red light?
it is short wavelength
What is the wavelenght of greenlight?
Green light typically has a wavelength within the region of 495-570 nm
What is the wavelenght of uv rays?
Less than that of visible light, which is in the range of about 350-700 nm - so UV rays would have a wavelength below 350 nm.
What is the wavelenght of white light?
400 to 700 nm because white light is the mixture of all 7 coloured lights.
Which color of the visible light portion of the electromagnetic spectrum has the highest frequency and the most energy?
Violet, with a wavelenght between 380 and 450 nm, which is near the end of the visible light, next to the ultraviolet region. Be careful because talk about "colors" is quite dangerous. Firstly, different cultures has different names for the same color. In addition to this, due to the fact that the electromagnetic spectra is continuous (i.e., there are infinite's wavelenghts) it is impossible to say exactly which wavelenght is the limit of the visible region and, consequently, which is the color associate to this wavelenght. Usually (but it is a convention) it is said that visible region is between 380 and 750 nm.
Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?
Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .
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.
What is the wavelenght of 255 nm in meters?
255 nanometers is 0.000000255m
The portion of the visible spectrum that appears brightest to the human eye is around 560 nm in wavelenght which corresponds to yellow green. What is the frequency os 560 nm light?
5.36 times 1014 Hertz (535,344 GHz)
How do you calculate how much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
The energy is 18,263.10e4 joules.
An electron requires 4.4 x 10-19 J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
450 nm
How much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
548kJ
