Sample Question
Describe the photoelectric effect.

The photoelectric effect occurs at any frequency of light, but the intensity determines the number of electrons emitted.

The phenomenon where electrons are emitted from the surface of a metal after being exposed to light of a particular frequency called the threshold frequency. Light below the threshold frequency will not cause electrons to be emitted. Above the threshold frequency, the maximum KE of the electrons depends on the frequency of the incident light. The number of electrons emitted depends on the intensity of light, and not the frequency. Emission of electrons is instantaneous, and considers that light can act as particles called photons.

The photoelectric effect involves the emission of protons from a metal surface when exposed to light.

The photoelectric effect is a result of chemical reactions between light and the metal surface.

Sample Question
What is the relationship between needs, wants, and scarcity in economics?

Limited. Society has just enough resources to meet its needs but not its wants.

Abundant. Society has unlimited resources to produce and satisfy all its needs and wants.

Scarce. The desire of society (individual consumers, government, business) to obtain and use goods and services is unlimited and the objective of all economic activity is to satisfy these material wants. The problem lies in the fact that economic resources (land, capital, labor, enterprise) are limited or scarce and therefore society will not be able to produce and consume all the goods and services it wants. Economics, then, is the science of efficiency; concerned with allocating these scarce resources so as to achieve maximum fulfillment of our material wants.

Unlimited. Society can produce and consume all the goods and services it desires without any constraints.
