The brilliance of diamond is due to the total internal reflection. Refractive index of diamond is 2.42 whereas critical angle is 24.4°. Diamond is cut suitably so that light entering to diamond from any phase falls at an angle more than critical angle so that's why , it suffers multiple total internal reflection. Hence, it shines brilliantly.

Mohammad Anas 8 years, 1 month ago

Its in the syllabus....its works throught magnetic coupling which helps in forward biasing whic increase the curent in the circuit once the cureent reaches to the peak value no change in magnetic flux takes place so now the capacitor dischage and support on forward biasing dec which dec the cureent and now magnetic flux induced in opposite cycle which more reduces the support and hence current dec ...this cycle follows upto peak to zero value of current..

Angle of minimum deviation of a glass prism decreased because , violet light is maximum deviated and red light minimum deviation then violet light.

Aman Primium Pandey 8 years, 1 month ago

angle of minimum deviation would decrease as it is inversely proportional to wavelength of light.

First of all our purpose is to get current from the light not from the diode so we use it reverse biasing as we want that radiation produces current .....now the radiation energy is convertd in form of light..

When a charge is placed in a hollow spherical body/shell, the electric field experienced by it is zero. This process of protecting the charged body from external electric field by placing it inside a hollow body is called electrostatic shielding.
