Electromagnetic spectrum Electromagnetic waves are coupled time varying electric and magnetic fields, propagating in space, with the speed very close to that of light (3xx10^8 ms^-1) . An the orderly distribution and classification of electromagnetic waves according to their frequency or wavelength is called electromagnetic spectrum. electromagnetic waves inclued visible light, ultraviolet waves, infra red waves, X-rays, gamma-rays, microwaves and radiowaves. For taking photographs, during dense fog, smoke mist, etc, we use

Wavelength of light used in an opticla instrument are lambda_1=4,000 overset@A and lambda_2=5,000 overset @A ,then ratio of their respective resolving powers(corresponding to lambda_1 and lambda_2 ) is:

A colloidal solution is a type of mixture which consists of particles whose size varies between 1 and 1000 nanometres. In colloidal solution the particles are distributed evenly. During this process the particles do not settle down. This is one of the best know thing about colloidal solutions. Properties of colloids and their variation are a well-known area ever since the primitive age. The best example to prove their familiarity with us is that we know from very early times that coagulation of milk results in the formation of curd. Physical properties of colloids 1. The nature of the colloidal solution is heterogeneous i.e. unlike. These solutions dwell with two different phases : • Dispersed medium Dispersed phase. 2. Despite the fact that colloidal dispersions are unlike in description (nature), yet the dispersed fragments are not detectabJe by the human eye. This is due to the microscopic size of the particles in the solution. 3. The colour of the colloidal dispersion is determined by particles in the solution based on their size. The wavelengths of light that is absorbed will be longer ifthe size of the particle is large. 4. As a result of its size, the colloidal fragments can easily be passed through a traditional filter paper. However, these particles can be filtered by using membranes such as animal, cellophane, and ultrafilters. Give the name of membrane used for filteration ?
