Snell's Law:
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from one medium to another medium.
That is Sini/Sinr = Constant
This is known as a Snell's law.
The wedge Make a wedge from a piece of wood and drive it inside a table leg or some other heavy object. View that the wedge is a double inclined plane
Power is to be supplied from a source whose resistance is 20 K ? to a load of 100 ?. Would you consider it as a constant voltage source or current source? Explain. Ans. G

Show the mathematical relation connecting n,u,v and R for refraction at a spherical surface concave towards a point object in a denser medium producing a virtual image.
a sinusodal transverse wave is travelling on a string any point on the string
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
