What is the relationship between wavelength of light and photons?

The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.

Does wavelength affect number of photons?

Your premise about the number of photons and energy is not quite correct. They are related by λ = hc/ E photon where h is Plank’s constant, c is the velocity of light and λ is the wavelength of the photon. In a given packet of photons the total energy is proportional to the number of photons.

How is the size of the photon related to light?

Very roughly, the interaction range of a photon scales with its wavelength, so light of longer wavelength is more likely to interact with a conductive material than light of a shorter wavelength. In this way you could say the “size” of photon is basically the width of its wavelength.

Does longer wavelength mean more photons?

No, frequency and wavelength dictate the color. Brighter lights means more photons, since Einstein showed that for a given frequency the energy of a photon is constant.

What happens to light when you increase the wavelength?

As the wavelength of light increases the frequency decreases. Based on the last equation, wavelength and energy are also inversely proportional. Therefore, as the wavelength of light increases, A. frequency decreases and energy decreases.

Which wavelength corresponds to photons with a greater energy?

Since the blue light has a smaller wavelength (and hence a larger frequency f=cλ ), a photon of blue light carries more energy than a photon of red light. Again smaller wavelength corresponds to a greater energy.

What determines the wavelength of a photon?

The higher the frequency, the more energy the photon has. As the frequency of a photon goes up, the wavelength () goes down, and as the frequency goes down, the wavelength increases.

What occurs when the wavelength of a photon increases?

All photons travel at the speed of light. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.

Do smaller wavelengths move faster?

Related to the energy and frequency is the wavelength, or the distance between corresponding points on subsequent waves. You can measure wavelength from peak to peak or from trough to trough. Shorter waves move faster and have more energy, and longer waves travel more slowly and have less energy.

Why do shorter wavelengths have more energy?

The energy associated with a wave is directly proportional to its frequency. Hence, the higher the frequency, the shorter the wavelength and the higher the energy of the wave. Red light, then, has a lower frequency and is associated with less energy than blue light.
