Review the verified answer and explanation for this SPSC – Sindh Public Service Commission past-paper question on CampusFin.

In a photoelectric cell, the velocity of ejection of an electron emitted depends upon _______? Answer: Frequency of the incident light

The velocity of an ejected electron in a photoelectric cell depends on the frequency of the incident light and the nature of the target material. Higher frequency light provides more energy, resulting in a higher velocity for the ejected electrons. The material's properties, such as its work function, also determine the minimum energy required to free an electron and thus influence its final velocity.
