This problem is providing the energy of a photon of light as 2.95 × 10⁻¹⁷ J and it is required to calculate its frequency, according to the electromagnetic spectrum theory. At the end, the answer turns out to be 4.52x10¹⁶ Hz according to the following:
In chemistry, we use the electromagnetic spectrum in order to know how the wavelength, frequency and energy of particles are related to each other. In this particular case, we have a photon and the frequency can be calculated with the following arrangement:
[tex]E=h\nu\\\\\nu=\frac{E}{h}[/tex]
Whereas E is the energy, h the Planck's constant and ν the frequency. Thus, we plug in these first two to obtain:
[tex]\nu=\frac{2.95x10^{-17}J}{6.626x10^{-34}J*s}\\\\\nu=4.45x10^{16}s^{-1}=4.45x10^{16}Hz[/tex]
