b. An electron and a photon has the same wavelength of 0.21 nm. Calculate the momentum and energy (in eV) of the electron and the photon. (Given c =3.00x108 m s-1, h =6.63 x 1034 J s, me=9.11 x 10-31 kg, mp=1.67 x 1027 kg and e=1.60x1019 C)
How rapidly would each of the following particles be moving if they all had the same wavelength as a photon of red light (wavelength = 750 nm)?a. An electron of mass 9.10939 x 10^-28 g?b. A proton of mas 1.67262 x 10^-24 gc. A neutron of mass 1.67493 x 10^-24 gd. An alpha particle of mass 6.64 x 10^-24 g   Please don't provide handwriting solution
For light with a wavelength of 350 nm and with an intensity of /= 10-8 W/m², what is the number of photons/(m²s) in the light beam?
