"Compton scattering shows that light behaves both like a wave and a particle. At a large wavelenth, light behaves like a wave, but at a small wavelength it behaves like a particle, called photons. Whe ...

"Two-dimensional vectors have two components: an x vector and a y vector. Each of these vector components is a vector in the direction of one axis. The sum of the components of vectors is the original ...

"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 light in dis ...

"Physics mirrors are where light can be reflected and reconvened to form images. Two different types of mirror are concave and convex mirror with different properties. Two types of image formed by mi ...

"Lenses are curved glasses or transparent materials. The focus of convex lenses is where rays parallel to principal axis go. The focus of the concave lenses is where rays parallel to principal come f ...

"Physics is defined as a natural science which studies the dynamics of matter, energy and physical forces. Advanced physics relies upon Calculus to mathematically represent motion and acceleration. Ph ...

"The photoelectric effect is a tool that we use to determine how much energy electrons have. The photoelectric effect was explained by Albert Einstein in 1905 and states that when light shines on meta ...

"Changes in matter can be classified as either physical or chemical, like matter properties. Physical changes include changes in physical appearance but not composition. All changes in state of matter ...

"Centripetal force causes an object in motion to continue in a curved path rather than a linear one. If this force stops, the object will continue in a tangential linear path. An example of centripeta ...

"Many students call centripetal force centrifugal force, but the two are not the same. Centrifugal force is the reaction to centripetal force as explained by Newton's Third Law of Motion, but it is on ...
