Question

energy of a photons having wavelength 310 nm is

Answer 1

Answer:

6.41*10 raise to power -19

Explanation:

Energy=HC/wavelength

Here wavelength is 310nm=310*10 raise to power -9 m

H is planck's constant and C is velocity of light

Energy=6.626*10 raise to power -34*3*10 raise to power 8/310*10raise to power -9

Energy=19.878*10 raise to power -26/310*10 raise to power -9

Energy=19.878*10 raise to power -17/310

Energy= 0.064*10 raise to power -17

Therefore energy is 6.41*10 raise to power -19 Joules
