If we increase the brightness of violet light shining on a photosensitive surface we also increases the
A)number of electrons ejected per second.
B)kinetic energy of the ejected electrons.
C)threshold frequency.
D)time lag between the absorption of blue light and ejection of electrons.
E)none of the above

Question

Quizplus · Accepted Answer

The number of electrons ejected per second, also known as photoelectric current, is directly proportional to the intensity (brightness) of incident light, according to the photoelectric effect. Therefore, increasing the brightness of violet light will result in more electrons being ejected per second. The other options are not affected by changes in brightness.
