Optics is a branch of physics that involves the properties of light and its interaction with matter. Reflection, refraction and diffraction are different ways light can behave based on the conditions ...

Most people know that light travels in a straight line unless something acts upon it to change its direction. The three most common methods of changing the direction of light are refraction, ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
