Question

calculate the wavelength of a photon whose energy is 2 electrons volt​

Answer 1

Explanation:

Hey mate We know the formula for Energy of photon

i.e E=hc/wavelength

E=(6.6*10^-34)*(3*10^8)/Wavelength

2=(2*10^-24)/wavelength

wavelength=(2*10^-24)*2

Wavelength=4*10^-24

Hope it helps

Thank you
