Question

These answers are wrong according to webassign, can someone please fix this?

Kinetic energy K = 3.5 x10 5 eV = 3.5 x10 5 x1.6 x10 -19 J

Where h = planck's constant = 6.625 x10 -34 Js

          m = mass of electron = 9.11 x10 -31 kg

(b) the ratio of this wavelength to the wavelength of light at the middle of the visible spectrum (550 nm)

   = (2.074x10 -12 m) /(550x10 -9 m)

   = 3.77 x10 -6

(c).required magnification is theoretically possible with this microscope than with a light microscope

is = 1/(3.77 x10 -6 ) = 265.18 x10 3

Explanation / Answer

your calculations are perfectly correct

every thing is perfect

i think you have taken the wrong values for kinetic energy

Once check the Kinetic energy value and comment below i will help further

basically you are correct both conceptually and mathamatically so just check the given values
