What is the relationship between frequency and wavelength of light?
What is the relationship between frequency and wavelength of light?
Frequency and wavelength are inversely proportional. Higher frequency means shorter wavelength, and lower frequency means longer wavelength.
As the frequency of light increases, the energy of the photons also increases.
As the frequency of light increases, the energy of the photons also increases.

Study Notes
Electromagnetic Spectrum Relationships
- Speed of light = wavelength x frequency (C = Av)
- Higher frequency = higher photon energy, shorter wavelength
- Lower frequency = lower photon energy, longer wavelength
Electromagnetic Spectrum
- Ranges from radio waves to gamma rays
- Wavelengths are measured in meters
- Radio waves have the longest wavelength and lowest energy
- Gamma rays have the shortest wavelength and highest energy
- Examples of types of EM radiation: Radio, Micro, Infrared, Visible, Ultraviolet, X-ray, Gamma
Water Solubility
- Water is a polar molecule.
- Polar molecules dissolve other polar molecules.
- Nonpolar molecules do not dissolve in water.
- Iron(III) hydroxide and hexane are not very soluble in water because they are not polar.
