In the systematic study of the photoelectric effect experiment, the stopping potential depends (for a given metal):
- A Intensity of the incident light (radiation)
- B amplitude of the incident light (radiation)
- C Frequency of the incident light (radiation)
- D Exposure time of the incident light (radiation)
Answer & Solution
Correct Answer
(C) Frequency of the incident light (radiation)
Step-by-step Solution
Detailed explanation
The stopping potential is directly proportional to the maximum kinetic energy of emitted photoelectrons, which depends solely on the frequency of the incident light for a specific metal. Changes in intensity only affect the number of photoelectrons (photoelectric current), not…

Broadly, genetic disorders may be grouped into two categories - Mendelian disorders and Chromosomal disorders. Mendelian disorders are mainly determined by alteration or mutation in the single gene. These disorders are transmitted to the offspring on the same lines as we have studied in the principle of inheritance. The trait may also be linked to the sex chromosome as in case of haemophilia. It is evident that this X-linked recessive trait shows transmission from carrier female of male progeny.
