Calculate the wavelength associated with 1 mev electron

1.	Calculate the wavelength associated with 1 mev electron
Answer» F=frequency (in per second) W= wavelength(in metre) E=energy(in joule) C= velocity of LIGHT(3×10^8m/s) h=planks constant(6.65×10^-34) E=hF F=C/W E=hC/W we have to find W E=1Mev= 1.6×10^-19 ×10^6 E=1.6×10^-13 (1EV= 1.6×10-19 Joule 1M=10^6 Joule) Now, hC=6.65×10^-34×3×10^8 hC= 2×10^-25 W=hC/E W=2×10^-25÷1.6×10^-13 W=20 ×10^-12÷16 W=1.25×10^-12metre I hope this is the answer if I am wrong then please LET me know

Answer»

F=frequency (in per second)

W= wavelength(in metre)

E=energy(in joule)

C= velocity of LIGHT(3×10^8m/s)

h=planks constant(6.65×10^-34)

E=hF

F=C/W

E=hC/W

we have to find W

E=1Mev= 1.6×10^-19 ×10^6

E=1.6×10^-13

(1EV= 1.6×10-19 Joule

1M=10^6 Joule)

Now,

hC=6.65×10^-34×3×10^8

hC= 2×10^-25

W=hC/E

W=2×10^-25÷1.6×10^-13

W=20 ×10^-12÷16

W=1.25×10^-12metre

I hope this is the answer if I am wrong then please LET me know
