How did Einstein used Plank' theory to explain the existence of threshold frequency?
Einstein used Planck's theory of quantization to explain the photoelectric effect by proposing that light is quantized into packets of energy called photons. These photons have energy proportional to their frequency, and when light with frequency below the threshold frequency interacts with a metal surface, no electrons are emitted. Above the threshold frequency, each photon can transfer enough energy to overcome the work function of the metal, causing electrons to be emitted.
What form of electromagnetic radiation has the highest frequency and energy?

Minimum frequency generated by radioactive nuclei?
The minimum frequency of radiation emitted by a radioactive nucleus is proportional to its energy. This frequency is related to the energy by the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency. Therefore, the minimum frequency of radiation emitted by a radioactive nucleus depends on the specific energy released during the radioactive decay process.
What is the smallest amount of energy that can be emitted or absorbed as electromagnetic radiation?
The smallest amount of energy that can be emitted or absorbed as electromagnetic radiation is a photon, which behaves like a particle carrying discrete energy. This minimum amount of energy is determined by the frequency of the radiation, according to Planck's equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
What is the link between energy and frequency for electromagnetic radiation?
The higher the frequency, the greater the electromagnetic energy. High-frequency gamma rays are the most energetic form of radiation (and the most dangerous to human health), followed by X-rays, ultraviolet, visible light, infrared (heat), and finally radio waves. Microwaves are actually a form of radio waves in the near-infrared. What makes them so apparently energetic (and therefore so useful) is that their particular frequency is great at making water molecules vibrate, which imparts heat energy directly into food in a process known as dielectric heating. E=hv Where E is energy h is planks constant v is the frequency of the EMr
Why for a particular metal electrons are emitted only when the frequency of the incident radiation is greater than a certain value?
Electrons are emitted from a metal surface when the energy of the incident photons is great enough to overcome the work function of the metal. This minimum energy required is equivalent to a certain threshold frequency, known as the threshold frequency. Electrons can only be emitted when the frequency of the incident radiation is greater than this threshold frequency because lower frequency photons do not possess enough energy to overcome the work function and release electrons from the metal surface.
How are energy and frequency of electromagnetic radiation related?
Energy = hf where h is Planck's Constant and f is the radiation frequency.
How are the energy and frequency of electromagnetic radiation related?
Energy and frequency of electromagnetic radiation are directly proportional. This means that as the frequency of radiation increases, so does its energy. This relationship is described by the equation E = h * f, where E is energy, h is Planck's constant, and f is frequency.
What is meant by the frequency of radiation?
The frequency of radiation refers to the number of wave cycles that pass a given point in one second. It is closely related to the energy of the radiation, with higher frequency radiation having higher energy levels. Radiation with higher frequency can be more harmful to living organisms.
When describing electromagnetic radiation there is a(n) relationship between wavelength and frequency and the greater the frequency the energy the electromagnetic radiation has.?
Electromagnetic radiation consists of waves with different wavelengths and frequencies. The frequency and energy of electromagnetic radiation are directly proportional—higher frequency waves have higher energy. This relationship is described by the formula E=hf, where E is energy, h is Planck's constant, and f is frequency.
How is the threshold frequency related to work function?
The threshold frequency is the minimum frequency of light required to eject electrons from a metal surface (photoelectric effect). The work function is the minimum energy needed to remove an electron from the metal surface. The threshold frequency is directly related to the work function through the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency.
When describing electromagnetic radiation there is a(n) relationship between wavelength and frequency and the greater the frequency the energy the electromagnetic radiation has. A) direct less B) dire?
The relationship between wavelength and frequency in electromagnetic radiation is inverse - shorter wavelengths correspond to higher frequencies. Higher frequency radiation carries more energy, as energy is directly proportional to frequency in the electromagnetic spectrum.
How does threshold frequency relate to work function?
Threshold frequency is the minimum frequency of light required to eject an electron from a metal surface, while work function is the minimum energy required to remove an electron from the metal. The threshold frequency is directly related to the work function by the equation E = hf, where E is the energy required, h is Planck's constant, and f is the frequency of the incident light.
Does the energy increase as the frequency of the radiation decreases?
Does the energy of a photon increase as the frequency decreases ? No.In fact it is just the opposite : energy increases as the frequency increases.The relation is very simple; it's just e=hv wheree is the energy of the photonh is Planck's constantv is the frequency of the radiation.( v should be the Greek letter nu, but this keyboard won't do it ! )
Does photoelectric effect take place below threshold frequency?
No, the photoelectric effect only occurs when the frequency of incident light is equal to or greater than the threshold frequency. Below the threshold frequency, photons do not possess enough energy to eject electrons from a material.
What is threshold frequency in photoelectric effect?
Threshold frequency refers to the minimum frequency of incident light required to eject electrons from the surface of a metal in the photoelectric effect. Electrons will only be emitted if the frequency of light is equal to or greater than the threshold frequency, as lower frequencies do not possess sufficient energy to overcome the work function of the metal.
What does the frequency of a wave tell us about the energy or radiation of the wave?
The frequency of a wave is directly proportional to its energy or radiation. Higher frequency waves have higher energy, while lower frequency waves have lower energy. This relationship is described by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency.
