Question 9

A monochromatic light source illuminates a metal surface, causing photoelectrons to be emitted. If the intensity of the light is doubled while keeping its frequency constant, what would be the observed change in the photoelectric current and the maximum kinetic energy of the emitted photoelectrons?

Accepted Answer

A. Photoelectric current doubles, maximum kinetic energy remains constant. — Doubling the intensity of light, while keeping its frequency constant, increases the number of photons incident on the metal surface per unit time. This leads to a proportional increase in the number of emitted photoelectrons, hence doubling the photoelectric current. However, the maximum kinetic energy of the emitted photoelectrons depends solely on the frequency of the incident light and the work function of the metal, remaining unaffected by changes in intensity.

Answer

B. Photoelectric current remains constant, maximum kinetic energy doubles.

Answer

C. Both photoelectric current and maximum kinetic energy double.

Answer

D. Both photoelectric current and maximum kinetic energy remain constant.

Question 10

A teacher in an inclusive classroom notices that a student with a hearing impairment is struggling to follow group discussions. Which of the following strategies would be most effective in ensuring the student's full participation?

Accepted Answer

C. Ensuring clear visibility of the speaker, using visual aids, and encouraging peers to speak one at a time. — For a student with a hearing impairment, effective communication in group settings relies on maximizing visual cues and minimizing auditory interference. Ensuring clear visibility of the speaker (for lip-reading), supplementing with visual aids, and structuring discussions so only one person speaks at a time are proactive strategies that promote real-time participation. Options A and B are reactive and do not facilitate active, real-time engagement, while option D is a partial solution that doesn't fully address the challenges of group discussions.

Answer

A. Providing a transcript of the discussion after the class for the student to review.

Answer

B. Assigning a peer to summarize key points for the student after each discussion.

Answer

D. Moving the student to the front row for all activities to improve sound reception.
