It can be observed that electrons are ejected from a metal surface by
shining light onto it. According to the accepted wave theory, what change
should occur in the electrons being ejected by the metal? *
Their number should increase.
Their mass should decrease.
Their charge should reverse.
Their speed should decrease.

Answer 1

Their number should increase

Step-by-step explanation:

The photoelectric effect is a phenomenon that causes the ejection of electrons from that metal as light shined onto a metal surface. Only certain frequencies of light can cause the ejection of electrons. However, if the frequency of the incident light is too low then no electrons were ejected even if the intensity of the light was very high. If the frequency of the light was higher then electrons were able to be ejected from the metal surface even if the intensity of the light was very low.

According to the accepted wave theory, light of any frequency will cause electrons to be emitted. Kinetic energy emitted by the electrons depends upon the intensity of light.

According to the accepted wave theory, number of electrons being ejected by the metal should increase
