"Longitudinal waves are waves which move particles in the direction of the wave motion. They are the counterparts to transverse waves which move particles parallel to the direction of wave motion. " ...

"Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid ...

"Linear motion is the motion that is natural to an object: moving in a straight line. According to Newton’s First Law of Motion, an object not affected by any force will continue indefinitely in a str ...
"Amplitude measures how far a wave rises and falls. A wave's amplitude is defined as half the distance from its highest point to its lowest point. Amplitude is proportional to the energy of a wave, a ...

"Ampere's Law was discovered in 1819 by Ampere. Ampere's Law states that currents generate magnetic fields or in other words, whenever you have a current, there is a magnetic field circulate around it ...

"Light quanta, called photons, are the smallest discrete amounts of light. For light quanta, we use the formula the energy of a photon = planck's constant x frequency. Because this is the smallest dis ...

"The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = - distance of th ...
"According to Newton’s First Law of Motion, also known as the Law of Inertia, an object at rest remains at rest and an object in motion remains in motion until it is acted upon by an unbalanced force. ...
"According to Newton’s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. S ...
"Planck's constant, abbreviated h, is the ratio of photon energy to the frequency. Planck's constant is used in the blackbody radiation spectrum, which indicates that energy is carried by ...
