I think it’s already established that the tourists spend equal times on the bicycle. To minimise the overall journey time, each tourist...

I am currently a junior (soon to be senior) undergraduate physics major and decided to join the physics forums because I have already...

Hopefully you have a typo' and mean ##0.412MeV##. The wording (IMO) implies that it's OK for you to assume that (at least some of) the...

Think about distance instead of time.

I understand. Thank you very much for all the help and explanation haruspex, apostolosdt, nasu, Steve4Physics, hutchphd

Your Post #12 notes aren’t quite complete/accurate IMO. For example, compare this (improved IMO) version to the Post #12 version. For a...

Depends what is meant by a 'polariton' I guess. E.g. see this old thread...

Agreed. Agreed. Yes. The electrons leaving the metal surface are moving faster. (And this is true whenever frequency increases -...

I agree. My Post #8 explanation is (overly?) simplistic - but may be adequate to answer the OP’s question. In a crude model. photons...

No. It's not ideal to treat a photon as both a wave and particle at the same time. Nevertheless, for the purpose of explanation...

Continuity of the electromagnetic field leads to the frequency being the same. If the wave in the medium is driven by the wave incident...

You have to remember that the current you are considering is the saturation current. A few made-up example figures (no claims to be...

Hi @apostolosdt. You may be misinterpreting the context/wording of the question. We have a (nearly) monochromatic light (photon)...

I'll give it a go too! See if this helps. The battery is connected at ##t=0##. In the first tiny time-interval, from ##t= 0## to ##t...

FWIW here’s another approach. Suppose a launch (call it X) leaves stage M at 12:00. At the same moment, a launch from N is arriving...
