## anonymous one year ago What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters? (Planck’s constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s) 2.9817 x 10-40 joules 4.4143 x 10-19 joules 6.6745 x 10-26 joules second 9.9456 x 10-49 joules 19.864 x 10-26 joules/second

1. JoannaBlackwelder

E=hv E is for energy, h is plank's constant, and v is frequency of the em radiation

2. JoannaBlackwelder

And $\nu=\frac{ c }{ lambda }$

3. JoannaBlackwelder

where lambda is wavelength and c is the speed of em radiation
