In the photoelectric effect, stopping potential is the minimum negative potential applied to the collector plate that completely stops the most energetic photoelectrons from reaching it, thereby reducing the photocurrent to zero. It represents the maximum kinetic energy of photoelectrons. For more vRead more

In the photon nature of light, the intensity of light is determined by the number of photons incident per unit area per second. A higher photon count corresponds to greater energy delivery, thereby increasing the light's intensity. For more visit here: https://www.tiwariacademy.com/ncert-solutions/cRead more
In the photon nature of light, the intensity of light is determined by the number of photons incident per unit area per second. A higher photon count corresponds to greater energy delivery, thereby increasing the light’s intensity.
In the photon picture of light, the intensity of radiation is defined as the energy delivered per unit area per unit time by the photons. It is proportional to the number of photons striking a surface per second. Its SI unit is Watt per square meter (W/m²). For more visit here: https://www.tiwariacaRead more

For a photosensitive material with constant frequency of incident radiation, the photocurrent increases linearly with the intensity of incident light. This is because a higher intensity of light emits more photons, leading to the ejection of more photoelectrons, thus increasing the photocurrent. ForRead more

Photoelectric emission occurs only if the frequency of incident light exceeds the material's threshold frequency. Below this frequency, photons lack sufficient energy to overcome the work function, the minimum energy required to eject electrons from the material's surface, making emission impossibleRead more

For a given photosensitive material and with a source of constant frequency of incident radiation, how does the photocurrent vary with the intensity of incident light?
For a photosensitive material with constant frequency of incident radiation, the photocurrent increases linearly with the intensity of incident light. This is because a higher intensity of light emits more photons, leading to the ejection of more photoelectrons, thus increasing the photocurrent. ForRead more

Why is photoelectric emission not possible at all frequencies?
Photoelectric emission occurs only if the frequency of incident light exceeds the material's threshold frequency.
