@speci★lRel★tivity do you offer tutoring services?

C★n you give me ★ b★sic rundown of like qu★ntum mech★nics?
Ele⁻ctromagne⁻tic radiation, like⁻ light, trave⁻ls both as a wave⁻ and a particle⁻. The⁻ e⁻ne⁻rgy of the⁻ particle⁻ (which is calle⁻d the⁻ photon) is dire⁻ctly proportional to the⁻ fre⁻que⁻ncy of the⁻ wave⁻. This is a ve⁻ry small amount of e⁻ne⁻rgy pe⁻r photon, though, as individual photons are⁻ so small the⁻y e⁻ffe⁻ctive⁻ly have⁻ 'ze⁻ro' mass. If you be⁻am photons onto a me⁻tal surface⁻ with a) e⁻nough e⁻ne⁻rgy and b) e⁻nough fre⁻que⁻ncy, it will re⁻move⁻ e⁻le⁻ctrons from the⁻ me⁻tal surface⁻, be⁻cause⁻ e⁻ach photon carrie⁻s a ce⁻rtain amount of e⁻ne⁻rgy to transfe⁻r to the⁻ e⁻le⁻ctrons, and so be⁻low a ce⁻rtain fre⁻que⁻ncy (thus, be⁻low a ce⁻rtain e⁻ne⁻rgy thre⁻shold), this e⁻ffe⁻ct doe⁻s not occur, proving that light wave⁻s must also act as particle⁻s. This same⁻ wave⁻-particle⁻ duality e⁻xists within all matte⁻r, but wave⁻le⁻ngth de⁻cre⁻ase⁻s as mass or ve⁻locity incre⁻ase⁻, so it is ofte⁻n ve⁻ry hard to se⁻e⁻ this in e⁻ffe⁻ct. High-spe⁻e⁻d e⁻le⁻ctrons may be⁻ re⁻dire⁻cte⁻d if trave⁻lling through a crystalline⁻ structure⁻ in which the⁻ space⁻ be⁻twe⁻e⁻n atoms is close⁻ to the⁻ e⁻le⁻ctrons' wave⁻le⁻ngths.

Th★nk you.
