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.
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
What happens to a wavelength if no energy is supplied to it?
without energy there cannot be a wavelength.
What does the wavelength of an EM wave tell about its energy?
The shorter the wavelength of a wave, the higher its energy.
How are the energy and wavelength radiation related?
Energy and wavelength are related by Planck's Energy formula E = hf = hc/w where w is the wavelength.
How does the energy associated with waves change wavelength changes?
a shorter wavelength means lower energy. A shorter wavelength means high energy
How much energy does a wavelength have if it has a wave of 3.01x10-9m?
A wavelength doesn't have energy. The wave does. The details depend on the type of wave. Assuming an electromagnetic wave, you have to multiply the frequency by Plank's constant. To find the frequency, divide the speed of the wave by the wavelength.
What does a wavelength carry?
A wavelength carry energy. Strictly speaking, a wave carries energy. A wavelength is a property of a wave.
What does the wavelength of an em tell about it's energy?
As the wavelength decreases, the energy increases.
When wavelength increases frequency and energy do what?
Frequency and energy decrease as wavelength increases.
How are energy and wavelength of electromagnet radiation related?
The greater the energy the shorter the wavelength.
How do you find wavelength if you've been given the energy?
The easiest way would be to find a descriptive article on the internet that shows the visible colors spread out with some wavelengths labeled. There, you can find the approximate wavelengths for light of various colors. If you don't know the color of the light, then in order to find its wavelength, you'd need to know either its frequency or the energy of a photon (quantum). Energy of a photon = h f h = Planck's Konstant = about 6.63 x 10-34 joule-second f = frequency of the light wave or photon But the frequency is (speed of light)/(wavelength) so, Energy = h c/wavelength . If you know either the energy of the photon or its frequency, you can use this stuff to find its wavelength. In this discussion, I've toggled back and forth a few times between the frequency/wavelength of the quantum and the frequency/wavelength of the light wave. Don't worry. They're the same.
