What happens in photoelectric effect if both intensity and frequency of the source are doubled?

In a photoelectric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current.

What happens to kinetic energy when frequency is doubled?

be the final frequency. is the kinetic energy of photons in joules. From this, we found that kinetic energy increases by more than double.

What will the intensity be if the frequency is doubled?

If the only thing one changes is the frequency of the photons, then doubling the frequency will double the intensity. Alternately, doubling only the emission rate, or focusing the photons to hit half the area will also double the intensity.

Does photocurrent increase with frequency?

Thus increase in intensity should increase the photocurrent. When frequency is increased the energy of individual photons increases. The work function is fixed. Hence, the any increase in the energy of individual photons results in increase in maximum kinetic energy of the ejected electrons.

When intensity of light is doubled keeping frequency the same the energy of each photon doubles True or false?

Since frequency of light solurce is double, the energy carried by each photon will be doubled. Hence intensity will be doubled even if number of photons remains constant. Hence saturation current is constant. Since frequency is doubled, maximum KE increases but it is not doubled.

What frequency and intensity do in the case of the photoelectric effect?

1, just the opposite behavior is observed in the photoelectric effect. The intensity affects the number of electrons, and the frequency affects the kinetic energy of the emitted electrons.

What will happen to photocurrent IF frequency of incident light is doubled keeping intensity constant?

The saturation photocurrent remains almost the same B. The maximum kinetic energy of the photoelectrons is double. Since frequency of light solurce is double, the energy carried by each photon will be doubled. Hence intensity will be doubled even if number of photons remains constant.

What will happen to photocurrent IF frequency of incident light?

A. Depends both on intensity and frequency of the incident light. Increases with increase in frequency of incident light. …

What happens to photocurrent when intensity of light is doubled?

Why does photocurrent increase with intensity?

Intensity means that the no of photons incident on unit area in unit time. So if emission is possible , and if intensity increases the no of electrons emitted increases. In thsi way the current increases.

Does photocurrent depend on intensity?

A higher intensity of radiation produces a higher value of photocurrent. For the negative potential difference, as the absolute value of the potential difference increases, the value of the photocurrent decreases and becomes zero at the stopping potential.

What is the relation between intensity of light and frequency of light?

Answer: Light is electromagnetic radiation and exhbits dual nature, wave and particle. if you consider light is wave, intensity is related to light radiation energy and frequency is the number of waves per second. if you consider light is particle, each particle in the light radiation is called photon.
