How many electron volt in a hertz?

Answer 1

Hz is a unit of frequency and is equivalent to cycles per second.

The election-volt, or eV, is a unit of energy and represents the

increase in energy of an electron after accelerating through a

potential difference of 1 Volt.

The energy of a photon with frequency f is given by the Planck

formula E = hf, where h is Planck's constant. In terms of eV and Hz,

the units of h are eV/Hz, or more commonly eV-secs. The value

of h in these units about 4.1357e-15.

Hence, a photon with a frequency of 1 GHz will have an energy of

4.1357e-15*1e9, or about 4.1357e-6 eV. This energy is millions of

times smaller than the energy needed to break covalent bonds.

Answer 2

there are zero watts in a hertz. Watts is a measure of power. One Watt equals one Joule per second.

A hertz is a frequency or in actuality the inverse of a fequency 1/f and is ussually represented in cylces per second.
