do orbitals represent a region of space?

What would the speed of each particle be if it had the same wavelength as a photon of green light (λ=500.0 nm)? proton (mass=1.673×10−24 g) speed:   m/s neutron (mass=1.675×10−24 g) speed:   m/s electron (mass=9.109×10−28 g) speed:   m/s

If photons have a frequency of 1.818x1015 s-1, what wavelength, in nm, does this correspond to?

4

Which has the greater wavelength, blue light or red light? How do the frequencies of blue light and red light compare? How does the energy of blue light compare with that of red light? Does blue light have a greater speed than red light?
