Q Define: specific rotation?
Precise rotation for a given wavelength of light at a given temperature is defined as the rotation produced by one-decimetre length of the liquid column containing 1 gram of the active material in1cc of the solution.
That is S = θ / l c
How is Specific Gravity defined? Specific Gravity, SG, is a unit less quantity that provides the scientist or engineers an idea of how dense a substance is compared to water. T
Half shade and Biquartz
With a neat and clean diagram illustrate in brief the TIR. Describe critical angle and mention the two conditions for TIR.
background of motion in one dimension
Q. How much should be the voltage of an X-ray tube so that the electrons emitted from the cathode may give an X-ray of wavelength 1 A o after striking the target? λmin = 124
The variable resistor is a resistor whose value can be accustomed by turn a shaft or sliding a control. They are also referred to as potentiometers or rheostats and permit the resi
Q. Why X-rays are not used in microscopes? 1) The wavelength of X-rays is slighter than that of the visible light. 2) X-rays can't be focussed as visible radiations are foc
Self inductance: When current through a coil changes, the changing flux induces an emf that opposes the current flow. This emf is the result of self inductance and is called '
Q. Explain Snells Law? It is believed that Snell developed his well-known equation by purely empirical means. He made various measurements of the refracting properties of vario
