You can use Plank's relation to calculate the energy of the absorbed photon.
E = h.f = h.c/L
given
E = Energy of a photon in Joules
f = frequency of the photon in s-1
c = speed of light in m/s
L = wavelength of the photon in metre
h = Planck constant = 6.62606957×10−34 J.s

∙ 14y agoSolve
c = lambda*f
where lambda is wavelength, and f is frequency and c is the speed of light.
given two can find the third.
else, if energy is known
E = hf can E = hc / lambda can be applied to find frequency of lambda.

∙ 15y agospeed of light (C)= wavelength (?) x frequency (v) C is the constant in the equation which equals 3.00 x 108 The frequency would be given in the problem and from there you divide C/v

∙ 12y agoThe wavelength is the ratio between the speed of light and the frequency.
Wiki User
∙ 13y agoEnergy is related to wvelength by E = hc/wavelength = 2E-25/wavelengthm where h is Planck's Constant and c is the speed of light.

∙ 11y agoWave length = (speed)/(frequency)
'Speed' of the photons is the 'speed of light'.

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.
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 do you calculate wavelength from wavenumber?
Wave number=1/Wavelength=> Wavelength= 1/wave number
How do radio waves and x rays compare in terms of wavelength and energy?
Radio waves are longer than X-rays and because energy is inversely proportional to wavelength, X-Rays have more energy. The formula is 1.25uevm/wavelength, that is the energy is 1.25 micro electron volt divided by the wavelength in meters.
What does nm in calculation of ultraviolet rays mean?
nm = nanometers It is a measure of the wavelength of the light, with energy inversely proportional to the wavelength: E = h / wavelength
What does the wavelength of EM wave tell you about its energy?
It tells you that the longer the wavelength the lower the energy. From the wavelength, one can also calculate the actual energy by using E = cxh/lambda where c is speed of light, h is Plank's constant and lambda is the wavelength.

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.
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.
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 do you calculate how much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?

How do you calculate the energy of violet light emitted by a hydrogen atom with a wavelength of 410.1nm?
4.85*10^-19
What line spectrum of lithium has a red line at 670.8 nanometers calculate the energy of a photon with this wavelength?
178.334kJ/mol.
If you know the wavelength of an electromagnetic wave in a vacuum you can calculate its?
Momentum, energy, frequency, and wave number (but not wave vector.)
What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
A characteristic wavelength of an electron can be known as the DeBroglie Wavelength. It is a formula in physics which relays energy and momentum.
How do you calculate the wavelength?
Wavelength = (wave speed) divided by (frequency)
What happens to a wavelength if no energy is supplied to it?
without energy there cannot be a wavelength.
