Question

A) You are walking briskly across campus for your next class. What is your approximate deBroglie wavelength in meters? Please enter only the EXPONENT of your answer (for example, if your answer is 7.2E36, enter 36. If your answer is 7.2E-10, enter -10.)

B) In class proffesor mentions to his students that the two doors of the class hall could be considered as the slits of a double slit. Having in mind your answer from the previous question, should they be concerned that they may interfere with themselves by leaving the class?

Explanation / Answer

(a) lets assume mass of man= 100 lb = 45.36 kg

velocity= 4.75 miles per hour=2.123 m/s

debroglie wavelength= h/mv = 6.626 × 10-34 /(45.36* 2.123)= 6.88x10-36 m =10-36 m (exponent only)

(b) they should not be concerned about interfering as the wavelength associated with them is very small as compared to the wavelength of light and the size of slits is very large (door)
