Transition A produces light with a wavelength of 400 nm

In summary, the conversation discusses a problem involving two transitions, A and B, with different wavelengths and energies. The speaker is having difficulty solving this problem and is seeking assistance in understanding the equation that relates energy and wavelength of a photon. They also wonder how changing the energy would affect the wavelength.

I am having difficulty with this problem. I have solved all of the other ones and got them correct, but this one is stumpimg me.

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?

Help please.

I am not looking for the answer from anyone. I just need to know how to figure it out. I want to learn and need some assistance.

What is the equation relating energy and wavelength of a photon and how would changing the energy change the wavelength?

Answer in the spoiler. 1st Spoiler just has the equation, 2nd has a solution.
Eλ=hc
So for λ=400 nm E=Eo
2Eoλ=hc

So to get the same value for hc, λ must be half of the original value, so:
λ=200 nm.

Thanks so much for the help. I am having learning this, but it has been 20years since I have taken college algebra and there is much more going on here than algebra. Love the knowledge!

I'm assuming that when you double the frequency you double the energy? Which would equal halving the wavelength?

Ah I am late,your query has been answered already.

FAQ: Transition A produces light with a wavelength of 400 nm

What does it mean when transition A produces light with a wavelength of 400 nm?

When a transition from one energy level to another occurs, a photon (particle of light) is emitted with a specific wavelength. In this case, transition A produces light with a wavelength of 400 nm, which falls within the visible light spectrum and appears as the color violet.

How is the wavelength of light produced by transition A measured?

The wavelength of light is typically measured in nanometers (nm), which is equal to 1 billionth of a meter. In this case, transition A produces light with a wavelength of 400 nm, which is a relatively short wavelength compared to other forms of electromagnetic radiation.

What factors can affect the wavelength of light produced by transition A?

The wavelength of light produced by transition A can be affected by various factors, such as the energy difference between the two energy levels involved in the transition, the atomic structure of the element, and the presence of external forces like electric or magnetic fields.

What are some common applications of light produced by transition A?

The light produced by transition A with a wavelength of 400 nm can be used in a variety of applications, such as in fluorescent lamps, UV sterilization, and optical communication. It can also be used in scientific research and medical imaging techniques.

How does transition A differ from other transitions that produce light?

Transition A is a specific type of transition that produces light with a wavelength of 400 nm. Other transitions may produce light with different wavelengths, depending on the energy levels involved and the properties of the element. Additionally, the intensity and frequency of the light produced may also vary between different transitions.
