How Fast is an Electron with a De Broglie Wavelength of 1.6 Å?

AI Thread Summary
To find the velocity of an electron with a De Broglie wavelength of 1.6 Å, the equation v = h/(m × wavelength) is used, where h is Planck's constant and m is the mass of the electron. The unit Å refers to Ångström, a distance measurement commonly used in chemistry, equivalent to 0.1 nm or 1 x 10^-10 m. Understanding this unit is crucial for converting the wavelength into standard SI units for calculations. By substituting the values into the equation, the velocity of the electron can be determined. This approach highlights the relationship between wavelength and particle velocity in quantum mechanics.

Homework Statement


What is the velocity of an electron having a De Broglie wavelength that is approximately the length of a chemical bond? Assume this length to be 1.6 A


Homework Equations


wavelength= h/mv


The Attempt at a Solution


I fixed the equation to isolate the velocity

h/(m x wavelength)=v

However I am unsure what the unit A means beside the 1.6.
I thought wavelength is in a unit of measurement like m , nm
h is the plank's constant and
mass is the mass of an electron
 
Physics news on Phys.org
The unit Å stands for Ångström, a measure of distance commonly used in chemistry because it is on the order of the length of a chemical bond. 1 Å = 0.1 nm = 1 x 10-10 m.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
