$\\ \sf\bull\longmapsto E=hv$

$\\ \sf\bull\longmapsto E=(hc)/(\lambda)$

$\\ \sf\bull\longmapsto E=(6.626* 10^(-34)Js* 3* 10^8ms^(-1))/(4.25* 10^(-7)m)$

$\\ \sf\bull\longmapsto E=(19.878* 10^(-26)Jm)/(4.25* 10^(-7)m)$

$\\ \sf\bull\longmapsto E=4.677* 10^(-19)J$

$\\ \sf\bull\longmapsto E=4677* 10^(-16)J$

$\\ \sf\bull\longmapsto E=4677eV$
