what determines the wavelength of a photon?
158235
The wavelength of a photon depends on the frequency of radiation of the electromagnetic wave and is given by the relationship wavelength = speed of light/frequency.

Wavelengths of visible light are in the range of 400 to 700 nanometers (nm). In this appendix we consider the formulation of photon wavelength and energy as well as the absorption of a photon by an electron. All electromagnetic radiation, radio waves through x-rays, moves in vacuum at a universal speed.

Wavelength is the distance between identical locations on adjacent waves (see figure below). Frequency is the number of complete waves, or wavelengths, that pass a given point each second. All light travels at the same speed, but each color has a different wavelength and frequency.

The Visible Light Spectrum – Wavelengths of Colors NOTE: Wavelengths of visible light are measured in nanometers (nm). A nanometer is a unit of length equal to one billionth of a meter.

Light acts as a wave and can be described by a wavelength λ and a frequency ν. Because the speed of light is a constant, the wavelength and the frequency of light are related to each other: as one increases, the other decreases and vice versa.

Explanation: Frequency and wavelength are inversely proportional. c=f⋅λ (The speed of light is directly proportional to f and λ) .

it depend a n frequency of the photon and the wavelength of the photon. ... So this states that as frequency of the particle increase the velocity also increases. But it is directly proportional to wavelength and frequency is just an proportional constant. So we can say that as wavelength increases then velocity increases.

Wavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases. The inverse proportionality is illustrated in Figure 2. This figure also shows the electromagnetic spectrum, the range of all types of electromagnetic radiation.

Definition: Wavelength and frequency. Light is measured by its wavelength (in nanometers) or frequency (in Hertz). equals the distance between two successive wave crests or troughs. equals the number of waves that passes a given point per second.

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Early Quantum Physics The energy E of a photon is equal to hv = hc/λ, where v is the frequency of the electromagnetic radiation and λ is its wavelength.

Wavelength is an important parameter of waves and is the distance between two like points on the wave. The wavelength is calculated from the wave speed and frequency by λ = wave speed/frequency, or λ = v / f. A peak is the highest point of a wave, while the valley is the lowest point of a wave.

Wavelength is commonly designated by the Greek letter lambda (λ). ... Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

The wavelength and frequency of light are inversely proportional to each other. Ex) wave length of light increases= the frequency decreases. ... The light emitted by an electron moving from a higher to a lower energy level has a frequency directly proportional to the energy change in the electron.

They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light. FREQUENCY OF OSCILLATION x WAVELENGTH = SPEED OF LIGHT.

The wavelength determines the energy PER PHOTON (a “photon” being the name used these days for what Planck and later Einstein called a “quantum” of light). The shorter the wavelength, the greater the energy per photon. The intensity is the total energy per time arriving in a unit area.

The relationship between the frequency (the number of wave crests that pass by a certain point in a given amount of time) and wavelength for electromagnetic waves is defined by the formula, c = λ f, where c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.
