A ray of light is incident normally on an equilateral prism of refractive index 3/2 calculate devition.
Ans) since the prism is equilateral therefore angle of prism is 600 => angle of refraction is 300applying snell\''s law,,,,sini * 1=sin300 *sqrt(3)=>sini=sqrt()3 / 2,=> i=600
explain origin of dimagnetsm on the basis of its atomic structure
neutral point
Explain 'drift velocity of free electrons'? Derive Ohm's law on the basis of the theory of electron drift.
Why the fringes are in circular form and how does it form?
Q. Illustrate how do you find the refractive index of a liquid by using total internal reflection? Answer:- Using Snell's law n (1) = (n (2) x sin angle (2)) / sin angl
Brewster's law (D. Brewster) The extent of the polarization of light reflected through a transparent surface is maximum while the reflected ray is at right angles to the refra
Short Sightened OR Myopia: When a person can't able to see objects clearly but can see near objects clearly. This defect of vision is known as short sightedness.
Q. Illustrate the Newton s laws of motion? Answer:- 1. A body at rest will stay at rest and one in motion will remain in motion until and unless acted upon by an external
a yellow lamp emits light with a wavelength of 6.00E-7 meters. Calculate the frequency of the yellow light.
Ans) In the first one..... F=ma...the only force which acts is F...which causes an acc. of ''a'' to the body of mass m... and as the force=>F=ma but on the second... let .
