Small drops of oil formed by a sprayer are allowed to fall in between a positively charged upper metal plate and a negatively charged lower metal plate. The space between the two plates is irradiated with X-rays. This displaces some electrons of the air molecules, which consequently get attached t..

The knowledge of viscosity and its variation with temperature, helps us select a suitable lubricant for a given machine. Viscosity of organic liquids such as proteins and cellulose, helps us calculate their molecular weight and determine their shape. The knowledge of viscosity helps in stud..

The principle of quantisation of electric charge states that "in nature there is a smallest amount of charge and all other charges are integral multiples of this smallest unit ". That is, if e is the minimum charge then the total charge on the body is equal to ne where n is an integer. This fact t..

>(iv) The stopping potential depends on the frequency of the light falling on the metal and not on the intensity of light. (v) The photocurrent increases with the intensity of the incident light. Millikan made the first accurate measurement of cut-off voltage for sodium metal by using mon..
