For question 4 on Midterm 2 it asks to find the wavelength of the ejected electron, which I knew how to do; however 4b asks "can the wavelike properties of ejected electrons in part A be detected?" and this question threw me off can someone explain the conceptual answer to this question; does it relate to the speed of light at all? That's the only thing I could think of to answer this question
Can someone clarify, please

I'm not sure if this is correct, but I think part b is asking if the wavelength is too small to be detected. So you would just have to see if your final answer is a very very small number.

Miya is right. I believe the cutoff is 10^-18 for the wavelength. If the wavelength is smaller than that, as is the wavelength for objects such as a ball or a car, then wavelength properties cannot be detected, and that is why we say that these objects do not have wavelength properties.

I suggest watching the video module on this topic! I believe it was mentioned that the wavelength could be detected up to the negative 12 or 15 power, but I'm not exactly sure if an exact value was said.

Hi, I remember hearing in class that it was 10^-18. I'm not sure if you remember but in lecture, we did practice problems where the wavelength was something like 10^-31 and we came to the conclusion that because it was so small we would not be able to detect it. Hope that helps!

The question is essentially asking if the wavelength of the ejected electron is too small to be detected. I'm pretty sure this means is it smaller than 10^-18 power.
