infrared waves are often called heat waves because they

A wave motion, in which the particles of the medium oscillate about their mean positions at right angles to the direction of propagation of the wave, is called transverse wave. These waves can propagate through solids and liquids but not through gas..

. In these methods, the energy is said to be transferred in the form of waves. Other examples of energy propagation by transfer of matter are Electric current in a wire Air currents set up by unequal heating of the surface of the Earth Ocean tides in which energy is transmitted ..

>. Thus, the ripples spread outwards in circles of increasing radii, with P as centre. Let one end of a long rope be attached to a rigid support and the other end held in the hand. If the rope is jerked suddenly, by moving the hand in a single up and down motion as in figure(a) below, an impulse is..

>This is called as dual nature of mater. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated..

But mn = mass per unit volume = density ( r ) The transfer of energy per unit time per unit area, perpendicular to the direction of motion of the wave, is called the intensity (I) of the wave. In unit time, the wave will have traveled a distance v. Therefore,..

The AM radio waves which propagate from one point to another following the surface of Earth are known as ground waves or surface waves. This type of propagation is called ground wave propagation or surface wave propagation. In ground ..

The simplest type of wave is the one in which the particles of the medium are set into simple harmonic vibrations as the wave passes through it. The wave is then called a simple harmonic wave..

The branch of physics dealing with the study of optical phenomena is called optics. This can be divided into two categories, ray optics and wave optic..

Sky waves are the AM radio waves, which are received after being reflected from the ionosphere. The propagation of radio wave signals from one point to another via reflection from ionosphere is known as sky wave propagation. The sky wave propagatio..

Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment) - The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus..
