The interactions between current, the flow of electrons, and magnets can be used to do useful work, like power motors, and will continue to be important in the future because they can be used for thin ...
Light propagates, or travels, in waves. Waves have two main properties: frequency and wavelength. When you know one, it’s pretty easy to calculate the other.When light waves overlap they create interf ...
How fast does light travel, and does it travel faster in water or air? The fastest thing in the whole universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 108 ...

Optics is a branch of physics that studies the interactions of light with objects. Microscopes, cameras and other transparent “looking devices” use lenses to change the way we see objects. Using magni ...
Have you ever gone to make a sandwich only to discover that the last two slices of bread have mold on them? We are always told to use soaps and hand sanitizers to clean our hands of tiny organisms, bu ...
