Dear user,Formula used :E=hcλwhere h is universal planck's constantc is speed of light in vaccumand λ is wavelengthon putting the values,we get     =6
626×10-34×3×1084
86×10-7     =4 07×10-19 J

1) A green line of wavelength 4.86 x 10-7 m is observed in the emission spectrum of hydrogen. Calculate the energy of one photon of this green light (HHW)
