Measure the length of FH and GK. Repeat the experiment for different values of angle of incidence. Record the result in tabular form Sl.No i FH GK FH GK 1. 2. 3. 4. ..

E.g., Water gas and producer gas from coke, coal gas from coal, Bio gas from animal dung, coke from coal, petrol, kerosine, diesel and furnace oil from petroleum, charcoal from wood Moreover different fuels give different amounts of heat on burning. The heat liberated in joules when one g..

If we evaluate the increase in volume of the liquid taking into account the expansion of the vessel also, then we say it is absolute expansion of the liquid. We can show that, The coefficient of absolute expansion of a liquid = coefficient of apparent expansion + coefficient of cubical expansion of..

>Now, suppose that the slab is cut lengthwise into two parallel slabs (fig.(b)) each of area A/2. If the current flowing through the full slab is I for a given voltage V, then the current flowing through each half -slab is I/2. Therefore, the resistance of each half - slab is twice that of original..

. The larger the volume, the longer it takes for sound traveling at approximately 345 ms - 1 , to traverse the distances between the reflecting walls. When surfaces exposed to sound waves are highly absorbent, the rate of energy absorption by all surfaces quickly becomes equal to the rate of energy..

The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is devoted to t..

Reflection of Light - It is a matter of common experience that the objects inside a dark room, which are invisible, become visible when the room is illuminated by a source of light. Thus light can be defined as the external cause responsible for the sensation of visio..
