The Intriguing Photoelectric Effect

What is the photoelectric effect and how does it relate to the threshold frequency of a metal?

Can we calculate the threshold frequency of a metal based on the given data?

The Photoelectric Effect and Threshold Frequency

The photoelectric effect involves the ejection of electrons from a metal surface due to the impact of photons of sufficiently high frequency. The threshold frequency is the minimum frequency a photon requires to eject an electron.

From the information provided in this question, we cannot calculate the threshold frequency.

Understanding the Photoelectric Effect

The photoelectric effect is a fascinating phenomenon in which electrons are emitted from a metal surface when exposed to light of a certain frequency. This process plays a crucial role in understanding the interaction between light and matter.

Threshold frequency, on the other hand, is the minimum frequency required for a photon to eject an electron from a metal. It varies for different metals and is a key parameter in studying the photoelectric effect.

When a photon with a frequency of 1 x 10^15 sec-1 hits a metal surface and ejects an electron with a kinetic energy of 1.988 x 10^-19J, we cannot determine the threshold frequency of the metal without knowing the work function of the metal. The threshold frequency is directly related to the work function, which was not provided in the given data.

Therefore, without additional information about the work function of the metal, we cannot calculate the threshold frequency. To fully grasp the intricacies of the photoelectric effect and how it manifests in different metals, a comprehensive understanding of the interplay between photon energy, work function, and threshold frequency is essential.
