Sound and light are two fundamental aspects of experiencing life. For example, sound waves can be reflected off a surface, like an echo, and light can also be reflected, such as when people see themselves in a mirror. Although sound and light waves travel in slightly different ways, vibration is always the source of the motion. Sound and Light explores both types of waves from how they are generated to how they interact with the world around them. Understanding the way sound and light interact can answer frequently asked questions, such as why the ocean is blue and why the siren on an...

Electromagnetism is the force that causes attraction and repulsion between charged particles and between magnets. This force is responsible for almost all interactions, including how a car runs, how electronic equipment is powered, and how high-voltage electricity from a power plant is converted to a lower voltage for use in the home. Electricity and Magnetism explains the basics of electromagnetism, including what electricity and magnetism are and how they interact with each other, giving physics students a complete understand of this fundamental force.
