Question

an electron has a mass 9.108*10-³¹ kg and velocity 0.6*10*8 ms-¹ calculate the wave length of the electron​

Answer 1

Answer:

Explanation:

Given Data:

Mass= 9.108*10^-31 kg

Velocity= 0.6* 10^8 ms^-1

Formula being used:

λ=h/mv

Solution:

h is a planck's constant having value = 6.63*10^-34

Putting values:

λ=6.63*10^-34/(9.108*10^-31) × (0.6*10^8)

λ=1.2142 * 10^-11 m

So,the wavelength is 1.2142*10-^11 m
