Question

In the ultra-violet region of atomic spectrum of hydrogen, a line
is obtained at 1050 Å Calculate the energy of one million
photons of this wavelength

Energy E=N hcλN= Number of photons = 1 million = 106 h= Planck's constant = 6
626 ×10-34 J secc= Velocity of light = 3 × 108 m/secλ = Wavelength = 1050 A0 = 1050 × 10-10 mOn substitutingE= 106 × 6
626 ×10-34 ×3 × 108 1050 × 10-10   = 0
01893 × 10-10 J

In the ultra-violet region of atomic spectrum of hydrogen, a line is obtained at 1050 Å. Calculate the energy of one million photons of this wavelength.
