In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

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 ...

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, ...

GNSS signals caused by reflection and diffraction. The signals: green denotes LOS signals, red and purple denote reflected signals, and blue and yellow denote diffracted signals. Disclaimer: AAAS and ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
