Abeam of laser light is ab a beam of laser light is absorbed by a collection of ground-state hydrogen atoms. after the absorption, the excited hydrogen atoms emit three different wavelengths when they relax back to the ground state. determine (1) the quantum number of the state after the excitation, (ii) the wavelength of the laser light, and (iii) the largest emission wavelength.

a displacement distance is size of displ

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
