Final answer:

The photoelectric effect is a phenomenon in which light shone onto a metal surface causes the ejection of electrons. Copper is a metal that exhibits the photoelectric effect. When it is irradiated with electromagnetic radiation with a frequency of 150 nm, electrons will be emitted from the copper surface.

Step-by-step explanation:

The photoelectric effect is a phenomenon that occurs when light shone onto a metal surface causes the ejection of electrons from that metal. Only certain frequencies of light, above a certain threshold frequency, can cause the ejection of electrons. Copper is a metal that exhibits the photoelectric effect. When it is irradiated with electromagnetic radiation with a frequency of 150 nm (ultraviolet range), electrons will be emitted from the copper surface.
