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.
The phase of weightlessness may be observed in the following situations: (i) When objects fall freely under gravity : For example, a lift goes down freely, or an airship showing
Study of a rolling ball A large ball bearing or 'bagatelle ball' rolling down a smooth track can be timed by a pendulum. To make the track, fasten together two 120 cm lengths o
Derivation
The energy possessed by a object by virtue of its position or its configuration is called its potential energy. Concept of potential energy is valid only in conservative field.
Lorentz was the first to obtain the equations which relate the space and time coordinate of two frames of reference moving with a constant velocity with reference to each other and
Newton''s rings are formed between a spherical lens surface and an optical flat. If the tenth bright ring of green light (545.1 nm) is 7.89 mm in diameter, what is the radius of cu
CPH has rest mass, so how it explained by relativity? Answer; never can we see CPH at rest condition. CPH moves faster than light.
Two wattmeters indicate 10 kW and 3 kW respectively when linked to measure the input power to a 3-phase balanced load, the reverse switch being operated on the meter showing the 3k
