Newton's Corpuscular Theory:
Newton's corpuscular theory of light states that
1. Light is emitted form of tiny particles is known as corpuscles.
2. The corpuscles travel with the velocity of light.
3. When corpuscles strike the surface they caused to sensation of light.
4.Medium is essential for propagation of light.
5. Velocity is greater in denser medium as compared to rare medium.
6. The velocity of light depends upon the temperature of the body emitting the light.
Magnus effect: In a moving fluid a rotating cylinder drags some of the fluid around with it, in its direction of rotation. This enhances the speed in that region, and therefor

Define the physical significance of damping coefficient and how can we caluclate it? What is its unit
A transformer takes a current of 0.8A when its primary is connected to a 240 volt, 50Hz supply, the secondary being on open circuit. If the power absorbed is 72 watts, Determi
Explain about the inverse piezoelectric effect. Inverse piezoelectric effect: While an alternating e.m.f is applied to the opposed faces of a quartz or tourmaline crystal th
Power factor improvement: The low power factor is because of the fact that most of the power loads are inductive and thus take lagging currents.
