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 ...

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 ...

A finite element wave propagation model for linear periodic waves in a coastal sea region is developed. The model includes refraction, diffraction, and reflection of gravity waves on water over ...

According to the World Meteorological Organization, a photometer is “an optical phenomenon produced by the reflection, refraction, diffraction or interference of light from the sun or the moon.
