An electron is moving with kinetic energy 40.5 into 10^-25 calculate its de brogleis wavelength....
answer fast please....
Answers
Answer:
Answer: The de-Broglie wavelength of an electron is
Explanation:
De-Broglie wavelength is calculated by using the formula:
.....(1)
where,
= wavelength of electron
h = Planck's constant =
m = mass of electron =
v = velocity of electron (to be calculated from kinetic energy)
Formula used to calculate kinetic energy of an electron is given as:
Putting values of energy and mass in above formula, we get:
Now, putting all the values in equation 1, we get:
Hence, the de-Broglie wavelength of an electron is1. 025
