Which scientist stated that particles "stream" and each particle of light carries a quantum of energy?

a) einstein
b) planck
c) schrodinger
d) bohr

Einstein’s photons of light were individual packets of energy having many of the characteristics of particles. Recall that the collision of an electron (a particle) with a sufficiently energetic photon can eject a photoelectron from the surface of a metal. Any excess energy is transferred to the electron and is converted to the kinetic energy of the ejected electron. Einstein’s hypothesis that energy is concentrated in localized bundles, however, was in sharp contrast to the classical notion that energy is spread out uniformly in a wave. We now describe Einstein’s theory of the relationship between energy and mass, a theory that others built on to develop our current model of the atom.( ◑‿◑)ɔ┏--┑٩(^◡^ )( ◑‿◑)ɔ┏--┑٩(^◡^ )( ◑‿◑)ɔ┏--┑

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
