Visible light falls into wavelength ranges of 400-700 nm, for which 1 m =1 × 10° nm. The energy and wavelength of light are related by the equation hc E = where E is energy in Joules, h is Planck's constant (6.626 × 10-34 J-s), c is the speed of light ( 2.998 × 10° m/s), and A is the wavelength in m. If a visible light photon has a wavelength of 693.7 nm, what is the energy of the photon (in J)?

Question

Visible light falls into wavelength ranges of 400-700 nm, for which 

1 m=1×109 nm1 m=1×109 nm. 

 

The energy and wavelength of light are related by the equation

E=hcλE=hcλ

where
EE is energy in Joules,
hh is Planck's constant (
6.626×10−34 J-s6.626×10−34 J-s),
cc is the speed of light (
2.998×108 m/s2.998×108 m/s), and
λλis the wavelength in m.

 

If a visible light photon has a wavelength of 693.7 nm, what is the energy of the photon (in J)?

Visible light falls into wavelength ranges of 400-700 nm, for which 1 m = 1 x 10° nm. The energy and wavelength of light are related by the equation hc E -34 where E is energy in Joules, h is Planck's constant ( 6.626 × 10 J-s), c is the speed of light (2.998 × 10° m/s), and d is the wavelength in m. If a visible light photon has a wavelength of 693.7 nm, what is the energy of the photon (in J)? Type answer: ||
