A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase.
In comparison to air velocity of sound is main in water, as water is rarer phase for sound waves w.r.t. air. But it is not right for light (EM-waves). For light rays water is denser medium w.r.t. air.
One mole of H 2 at 300 K takes a volume of 10 lits in a cylinder fitted with a piston. It is expanded isothermally to 20 lits. Consider ideal behavior for the gas, determine W, Q,
Explain about the term pumping in laser. Pumping in laser is particular criteria to get laser output. It is same to pumping well water to the ground level or to an overhead tan
what will happen if gravity becomes zero?is it possible in earth?
Q The resistance of a platinum wire at 0 o C is 4 Ω. What will be the resistance at 100 o C, if the temperature coefficient of resistance is 0.0038/ o C. Resistance at 100 o
Two moles of an ideal gas expands reversibly and isothermally to ten times its volume at 25°C. Evaluate the change in entropy during the process. ( R = 8.314 JK -1 mol -1 )

Explain Shape of the earth? Shape and size of the earth. The shape of the earth is regarded as a sphere, but it is mainly an oblate spheroid like as egg being slightly flatter
how to get the formula ?.
Water at 20°C flows through a long, straight pipe. The pressure drop is measured along a section of the pipe of length 1.3 m as a function of average velocity through the pipe. Res
