What is the energy of an ultraviolet photon that has a wavelength of 1.67x10 with a negative exponent of 8 meters?

Answer 1

The energy of a photon of wavelength λ is given by hc/λ, where h is Planck's constant and c is the speed of light. Therefore, if λ = 1.67 x 10-8 m then:

Energy = (6.626068 x 10-34 Js)(299792458 m/s) / (1.67 x 10-8 m)

which is approximately 1.189 x 10-17 J, or 74.24 eV.

Answer 2

The energy of a photon can be calculated using the formula E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J-s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength. Plugging in the values, we get E = (6.626 x 10^-34 J-s * 3.00 x 10^8 m/s) / 1.67 x 10^-8 m = 3.76 x 10^-19 Joules.
