If light is a particle, what is wavelength / frequency ?

In summary, the conversation is discussing the relationship between light as a particle and its wavelength and frequency. The question is whether the wavelength of a particle is simply the same as the wavelength of the psi-function before measurement. There is also a deeper question about the nature of a particle's wavelength, such as the DeBroigle wave or the EM-wave for photons. The conversation also considers whether the question itself reveals a misunderstanding about quantum mechanics.

If light is a particle, what is "wavelength"/"frequency"?

Hello,

Is the wavelength of a particle simply the wavelength of the psi-function before measurement? Or (/and?) is it an intrinsic property that is "even there in the particle" when you measure the presence of the particle (i.e. reduction), like energy?

Or is the nature of this question exhibiting a deeper misunderstanding of mine?

My formal knowledge about QM doesn't extend beyond an introductory course.

Yes. Deeper question: what's the wavelength of particle? DeBroigle wave? - that is exactly the same. EM-wave for photon? - counterparts regarding different (QM / wave optics) approaches
Or is the nature of this question...
Probably "and" not "or" :devil:
 

FAQ: If light is a particle, what is wavelength / frequency ?

What is the relationship between wavelength and frequency of light particles?

The wavelength and frequency of light particles are inversely proportional to each other. This means that as the wavelength increases, the frequency decreases, and vice versa.

How does the wavelength of light affect its properties?

The wavelength of light determines its color and energy. Shorter wavelengths correspond to higher energy and bluer colors, while longer wavelengths correspond to lower energy and redder colors.

What is the unit of measurement for wavelength and frequency of light particles?

The unit of measurement for wavelength is meters (m), while the unit for frequency is hertz (Hz). In some cases, frequency may also be expressed in cycles per second (cps) or revolutions per minute (rpm).

Are there any factors that can change the wavelength or frequency of light particles?

Yes, the medium through which light travels can affect its wavelength and frequency. For example, light travels slower in water than in air, causing its wavelength to decrease and frequency to increase.

How is the concept of wavelength and frequency of light particles used in practical applications?

The concept of wavelength and frequency is used in various fields such as optics, telecommunications, and spectroscopy. It helps in understanding the properties of light and how it behaves in different mediums.
