Difference between Concave vs Convex Lens: Isn’t physics one of those subjects that almost every student is scared of? Well why not, given the complexity of ...

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...

Biconvex lenses also known as double convex lenses are simple optical lenses with two convex spherical surfaces, surfaces which bulge out from the center. These two convex surfaces have the same ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

Aspheric lenses are designed to focus or collimate light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed a detachable acoustic lens that allows for easy adjustment of the focal length in ultrasonic ...
