Concept of Heat

Science > Physics > Thermal Properties of Matter and Thermodynamics > concept of Heat “Heat” refers to the transfer of thermal energy between substances due to a temperature difference. It’s a form of energy associated with the motion of atoms and molecules in a substance. Heat always flows from regions of higher temperature to regions […]

Science > Physics > Wave Motion > Numerical Problems on Wave Motion Set – 02 Wave velocity in medium does not depend on the frequency. It depends upon the Elasticity and inertia of the medium. When medium changes the wavelength and velocity of wave changes but the frequency remains the same. Thus n1 = n2. […]

No Comments on Introduction to Wave Motion

Science > Physics > Wave Motion > Wave Motion The motion that repeats itself after fixed intervals of time is called periodic motion. We know that oscillatory motion is a type of periodic motion. Oscillatory motion is defined as the to and fro motion of an object from its mean position. Examples: oscillation of simple […]
