Planck's constant, h, is 6.626 x 10-34 Js. The speed of light in a vacuum, c, is 3.00 x 108 m/s. Calculate the energy of ultravi
igomit [66]

Given the Planck's constant and the speed of light, the energy of the ultraviolet light with a frequency of 9.58×10¹⁴ Hz is 6.35×10¯¹⁹ J (Option C)

<h3>Data obtained from the question </h3>
  • Planck's constant (h) = 6.626×10¯³⁴ Js
  • Speed of light (v) = 3×10⁸ m/s
  • Frequency (f) = 9.58×10¹⁴ Hz
  • Energy (E) =?

<h3>How to determine the energy </h3>

The energy of the ultraviolet light can be obtained as follow:

E = hf

E = 6.626×10¯³⁴ × 9.58×10¹⁴

E = 6.35×10¯¹⁹ J
