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 ...

An optical fibre is a thin strand of high-quality glass. Light can be transmitted through it over very large distances. The optical fibre makes use of the 'total internal reflection' of light. When a ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

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 ...

CBSE Science Class 10 Chapter 9 Mind Map: Understanding science is a tough task that becomes a more tedious job if resources are limited. Chemistry, Physics, and Biology are the subjects of science.

The focus is on the same side of the lens as the object. The focus is on the opposite side of the lens as the object. The principal focus is situated outside the principal axis. The focal length on ...
