Wavelengths of Matter Ranking Task
The following solution is suggested to handle the subject “Wavelengths of Matter Ranking Task“. Let’s keep an eye on the content below!
Question “Wavelengths of Matter Ranking Task”
Rank these objects on the basis of their wavelength. (largest to smallest)
person v=4.5m/s
electron v=0.01c
red light v=c
proton v=0.01c
car v=27m/s
baseball v=41m/s
Answer
This problem can be solved using de Broglie wavelength.
To find the wavelength of the person or electron, the red light, the proton, the car or baseball, you can first use de Broglie wavelength.
To rank objects based on their wavelength, you can use the wavelengths of the person, electrons, red lights, protons, car and baseball.
Below is the expression for de Broglie wavelength:
