Question

The energy of photon is E=3.03×10^-19 then the wavelength is?

Answer 1

hey as you know that

E=hc/wavelength

where h=6.626×10^-34

now simply solve it you got your ans

Answer 2

Energy of photon =3.03×10^-19J

We know that:

C=3×10^8ms^-1

H=6.63×10^-34 Js

E=hc/wavelength

Wavelength=hc/E

= 6.56×10^-7m

=656nm..
