Difference Between Distance and Displacement
Distance and Displacement are used to measure the distance travelled. Both the quantities seem to mean the same thing, yet they have differences in their meaning and definition. So, let’s discuss …
Mass Flow Rate
The mass flow rate is defined as the mass of a liquid substance passing per unit of time. SI units are kilogram per second. The mass flow directly depends on …
Strain Energy
Strain Energy usually denoted by U is basically the energy stored in a body due to deformation. It is a type of potential energy that is stored in a structure …
Malus Law
Malus law helps us study of light intensity relation of the polarizer-analyzer. It plays a vital role in understanding the polarization properties of light. History The law was named after …
Surface Energy
Surface energy measures the disruption of intermolecular bonds that occur when a surface is created. It also goes by the name surface free energy or interfacial free energy. It can …
PIN Diode
A PIN diode is a diode with a large and undoped intrinsic semiconductor region which is wedged between a p-type and an n-type semiconductor region. Since they are used for …
Laser Diode
Laser diode (LD), also known as, an injection laser diode (ILD), or diode laser is a semiconductor device that is similar to a light-emitting diode that emits a single wavelength …
Fisheye Lens
A fisheye lens is an ultra-wide-angle lens designed for shooting wide angles, usually 180°. Fisheye lenses use a special mapping, instead of producing an image with straight lines of perspective. …
P-N Junction Diode
A P-N junction diode is one of the simplest semiconductor devices. This diode has the characteristic of passing current in only one direction. It is based on the p-n junction. …
