GSuppose you have a molecule moving in the negative x direction at velocity 5.60 ×106 m s −1 , while an incoming light wave approaches the molecule in the the positive x direction. If the source light has a wavelength of 435 nm, what wavelength does the molecule "see"? Explain why the molecule "observes" wavelength you calculated and why it is shorter or longer than the incident light wavelength.

if they have a finite resultant

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
