Particle Nature of Light - According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surfac..

According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we user a low intensity source, it ..

Right grade or particle size of talc is important. A coarse talc has poor adhesiveness and is abrasive. The particle size of talc should be less than 74 microns for face powder. The powder becomes soft, fluffy, light and transparent when the talc is of the right nature..

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Nature of Light - Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this beam of light becomes invisibl..

Intensive investigation by scientists over the years led to the development of a mental model known as 'dynamic particle model..

Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles and this beam of light becomes invisible if the room is dust free. ..

Sound is a form of energy. It is produced by the vibration of particles and it travels in a wave-like motion. The number of waves passing a point per second is called the frequency and its unit is Hertz (Hz). The pitch of the sound (high or low sounding) is measured by the frequency. Man..

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of the experimental..

Dual Nature of Matter and Radiation - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It ..
