What is a photon?

Question

a) is a packet of energy
b) can only be absorbed by electrons if they have enough energy to boost electrons to a higher orbit
c) contains an amount of energy that depends on their frequency
d) is the fundamental unit of electromagnetic energy
e) all of the above

Answer 1

e?

Answer 2

a - yes

b - no, other particles can absorb photons and also give them off so this answer isn't strictly accurate. Electrons do absorb photons in this way, but they are not the only particles and this is not the only way in which an electron can interact with a photon.

c - yes

d - yes

e - best answer. but a, c and d is more accurate than including b as its implies incorrect properties of other particles (ie - particles other than electrons)

if you are in university level physics classes and you are asking this question, I feel for you.

if you are a high school student taking physics to fill a science requirement you don't care about, I gave a correct answer.

its up to you to figure out what to do with all the answers you are given. either you do the school work yourself or you analyze the various answers to pick the 'most correct' one. either way, its work - you can't escape work; you can only change the nature of the work.

Answer 3

All of the above

Answer 4

I would have to say "e", based on my fond memories of high school physics. Every one of answers a to d seem to fit.

Answer 6

f) none of the above

Photon is just an assumption with ever-changing definitions to conceptualize light.

Answer 7

e. all of the above

Answer 8

its always all of the above
