Intensity, frequency, wavelength, energy
Can someone clarify the relationships between the intensity, frequency, wavelength, and energy of light? How do these impact electrons being ejected? Thanks!

Re: Intensity, frequency, wavelength, energy
The relationships between intensity, frequency, wavelength, and energy of light are fundamental concepts in the study of electromagnetic radiation. The relationship between wavelength, frequency, and the speed of light (c) is given by the equation: c = λv where c is the speed of light, λ is the wavelength, and ν is the frequency. Frequency is the number of oscillations or cycles of a wave that occur in one second. The energy of a photon is directly proportional to its frequency (ν) and inversely proportional to its wavelength (λ). The relationship is given by the equation E = hν, where E is the energy of the photon, h is Planck's constant (a fundamental constant), and ν is the frequency. Electrons are ejected when photons transfer their energy to electrons in the material. The energy of the ejected electrons depends on the energy of the photons, which, in turn, is related to the frequency of the light.
