Using the equation E = hc/λ we can find out how much energy a single photon of wavelength 193 nm has. E = Planck Constant * Speed of Light/193 nm
Answer:
The number of photons is 4.8x10^14
Explanation:
The frequency of wave is equal to:
[tex]f=\frac{c}{l}[/tex]
where c is the speed of light, l is the wavelength of wave. Replacing values:
[tex]f=\frac{3x10^{8} }{193x10^{9} } =1.5x10^{15} Hz[/tex]
The energy of the proton is:
[tex]E=hf[/tex]
where h is the Planck´s constant. Replacing
[tex]E=6.626x10^{-34}*1.5x10^{5}=1.03x10^{-18} J[/tex]
The number of photons is:
[tex]n=\frac{E1}{E}[/tex]
where E1 is the energy of photon. Replacing:
[tex]n=\frac{0.5x10^{-3} }{1.03x10^{-18} }=4.8x10^{14}[/tex]
