Question

notation or the approprlate nmeulop 7. Find the energy (in joules) of a photon with a wavelength of 3.5 x 10 m. Be sure to include dimensional analysis and consideration of significant figures in your work. Also explicitly show any algebraic steps you use. Your answer should be reported using scientific notation. 8. Find the wavelength ofan electron moving at 15% the speed of light. Be sure to include dimensional analysis and consideration of significant figures in your work. Also explicitly show any algebraic steps you use

Explanation / Answer

7)

we have:

wavelength = 3.5*10^-7 m

we have below equation to be used:

Energy = Planck constant*speed of light/wavelength

=(6.626*10^-34 J.s)*(3.0*10^8 m/s)/(3.5*10^-7 m)

= 5.7*10^-19 J

Answer: 5.7*10^-19 J
