What is the frequency of a 5.35 x 10-3nm wave?• What is the wavelength (in nm) of a wave with a frequency of 9.45 x 1016Hz?

You would do 1500/4 and the answer is 375

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
