The frequency of a photon is inversely proportional to its wavelength. The higher the frequency, the shorter the wavelength. The energy of a photon is directly proportional to its frequency. So, a photon with an energy of 4.38 × 10-18 j has a frequency of 1.42 × 1018 Hz.

### Q: What is the frequency S 1 of electromagnetic radiation that has a wavelength of 0.53 m?

A: The frequency of electromagnetic radiation is given by:

f = c/λ

where c is the speed of light in a vacuum and λ is the wavelength of the radiation.

Therefore, the frequency of the electromagnetic radiation with a wavelength of 0.53 m is:

f = 3.0 x 10^8 m/s / 0.53 m

f = 5.7 x 10^7 Hz
