Can you calculate the energy of a photon of wavelength 11.56 meters, (Planck’s constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s)?

Answer:

The energy of the photon is #1.718 xx 10^(-26) "J"#.

Explanation:

The energy of the photon is #1.718 xx 10^(-26) "J"#.

You use the formula #E = (hc)/λ#, where #h# is Planck's Constant, #c# is the speed of light, and #lambda# is the wavelength of the photon.

#E = (hc)/lambda = (6.626 × 10^(-34)"J"*"s" xx 2.998 xx 10^8 "m"*"s"^(-1))/(11.56"m")# = #1.718 xx 10^(-26) "J"#
