Photoelectric current depends on

In photoelectric effect, the photo current:. The photoelectric current depends on intensity but is independent of the frequency. So, this option is incorrect. Byju's Answer.

Use app Login. In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light. Open in App. Verified by Toppr. The correct option is B does not depend on the frequency of incident light but depends on the intensity of the incident light. Photoelectronic current depends on the intensity of the light and is independent of the frequency of incident light.

Photoelectric current depends on

When the light of sufficiently small wavelength is incident on the metal surface, electrons are ejected from the metal instantly. This phenomenon is called the photoelectric effect. Last updated on Feb 9, This is a great opportunity for Engineering Graduates. Get Started. English Hindi. This question was previously asked in. Answer Detailed Solution Below Option 2 : 1, 2 and 3. Start Now. The photocurrent generated depends on the following factors: 1 Frequency of the incident light Frequency is an important factor because it decides whether the effect will take place or not. For photoelectric current, we first need the photoelectric effect. And it is kick-started by the frequency. If the frequency is high enough to eject electrons, that's it, the effect starts. More will be the number of photons, more will be the electrons no. So higher intensity, more no.

Assertion :In photoelectric effect, at stopping potential emission of photo-electrons is stopped.

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. The process through which photoelectrons are ejected from the surface of the metal due to the action of light is commonly referred to as photoemission. The photoelectric effect occurs because the electrons at the surface of the metal tend to absorb energy from the incident light and use it to overcome the attractive forces that bind them to the metallic nuclei. An illustration detailing the emission of photoelectrons as a result of the photoelectric effect is provided below. The photoelectric effect was first introduced by Wilhelm Ludwig Franz Hallwachs in the year , and the experimental verification was done by Heinrich Rudolf Hertz. They observed that when a surface is exposed to electromagnetic radiation at a higher threshold frequency, the radiation is absorbed, and the electrons are emitted. Today, we study the photoelectric effect as a phenomenon that involves a material absorbing electromagnetic radiation and releasing electrically charged particles. To be more precise, light incident on the surface of a metal in the photoelectric effect causes electrons to be ejected.

Photoelectric current depends on

When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength or equivalently, above a threshold frequency , the incident radiation is absorbed and the exposed surface emits electrons. This phenomenon is known as the photoelectric effect. Electrons that are emitted in this process are called photoelectrons. The target material serves as the anode, which becomes the emitter of photoelectrons when it is illuminated by monochromatic radiation. We call this electrode the photoelectrode. Photoelectrons are collected at the cathode, which is kept at a lower potential with respect to the anode. The potential difference between the electrodes can be increased or decreased, or its polarity can be reversed.

In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light. The Photon Theory. This phenomenon is known as the photoelectric effect. So, this option is incorrect. Which of the following is correct related to properties of good of good insulating material? This phenomenon is called the photoelectric effect. What is photoelectric effect? The photocurrent generated depends on the following factors: 1 Frequency of the incident light Frequency is an important factor because it decides whether the effect will take place or not. This results in an increase in the photoelectric current. More will be the number of photons, more will be the electrons no. When the light of sufficiently small wavelength is incident on the metal surface, electrons are ejected from the metal instantly.

When light strikes materials, it can eject electrons from them. This is called the photoelectric effect , meaning that light photo produces electricity.
