What wavelenght is expected for light composed of photons

In summary, to determine the wavelength of light produced by an n=3 to n=1 transition in a hydrogen atom, you can use the formula E=hc/λ, where E is the energy of the transition, h is Planck's constant, c is the speed of light, and λ is the wavelength. After solving the formula, the resulting wavelength is 8.1*10^-6 m. For further information and confirmation, you can refer to your textbook or this online resource on electron transitions in atoms.

What wavelenght is expected for light composed of photons produced by an n= 3 to n=1 transition in a hydrogen atom?

How do u work this out? Iam pretty confused.

You should be able to find a formula for the energy of such transitions in your text, from the energy use E=hc/lamda to find the wavelength.

ok i did it and i got 8.1*10^-6 m.
Is that right? Thanxs.

1. What is a photon?

A photon is a fundamental particle of light that carries energy and has zero mass. It behaves both as a wave and a particle.

2. How is the wavelength of light determined by photons?

The wavelength of light is determined by the energy of the photons that make up the light. The higher the energy of the photons, the shorter the wavelength of light will be.

3. What is the relationship between wavelength and frequency of light composed of photons?

The relationship between wavelength and frequency of light is inverse. This means that as the wavelength decreases, the frequency increases and vice versa.

4. What is the expected wavelength for visible light composed of photons?

The expected wavelength for visible light composed of photons is between 400 nanometers (blue light) and 700 nanometers (red light).

5. How does the wavelength of light composed of photons affect its color?

The wavelength of light composed of photons determines the color of the light. Shorter wavelengths appear blue, while longer wavelengths appear red. The visible spectrum of light is made up of a range of wavelengths that correspond to different colors.
