Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. As a wavelength increases in size, its frequency and energy (E) decrease. What happens when the wavelength of the light is increased? When a photon collides with an electron then the effect of it is called Compton scattering where the photons interact with the electron, losing momentum and therefore increase in wavelength. In terms of photons, higher amplitude light means more photons hitting the metal surface. What Happens To Wavelength As Frequency Increases? Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.

OBJECTIVES: 1. understand the electromagnetic spectrum and the mathematical relationships between energy, frequency, and wavelength of light 2. calculate the wavelength, frequency, and energy of light using Planck's constant and the speed of light See Some Examples The light intensity only determines the number of photons and hence the number of photoelectrons. It does not store any personal data. When a photon interacts with an electron, the energy if the photon is given to the electron and if the photon has energy as big as the work function, the electron absorbing the photon energy can escape from the metal. 7. The quantum number which explains the line spectra observed as doublets in case of hydrogen and alkali metals and doublets and triplets in case of alkaline earth metals is the spin quantum number. For example, short wavelengths are high energy gamma-rays and x-rays, long wavelengths are low energy radio waves. I love to write and share science related Stuff Here on my Website. While this is generally correct, things change when the light intensity is very high. The relation that we now believe to be correct is that the wavelength of the photon decreases as the energy of the photon increases. This is an inverse relationship between wavelength and temperature. Wavelength the distance between any given point and the same point in the next wave cycle. a decrease in wavelength.
