Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this test object may go in a round way, in irrotational flow the test object will not rotate about an axis by its own center of volume. For a loose analogy, the rotation of a Ferries wheel is rotation; that of its passengers is irrotational.
The measurements taken in Ramdesns eyepiece more worthy (reliable) than Huygens eyepiece. Why? Describe critical angle. show its relationship with refractive index.

Q. Explain about Centrifugal force? The centrifugal force is F c =mv 2 /r, Where r is the radius of the orbit and m is the mass of the object and v is the velocity. The
What is damped and undamped eletromagnetic waves Ans) A damped wave is a wave whose amplitude of oscillation decreases with time, eventually going to zero.
