A Newton’s cradle is also called a Newton’s pendulum, Newton’s rocker or a ball clicker. It was named after the great physicist Sir Isaac Newton and was designed by Edme Mariotte. Newton’s cradle demonstrates the principles of conservation of energy and conservation of momentum with swinging spheres. Newton’s cradle consists of several balls […]
The phenomenon in which the phase velocity of a wave depends on its frequency is called dispersion. Sometimes the term chromatic dispersion is used for specificity to optics. ref. A medium having this common property may be termed a dispersive medium. This term is used in the field of optics to describe light and other electromagnetic waves. Dispersion in the same sense can apply to any […]
When white light from the sun enters the earth’s atmosphere, the light gets scattered. Here the light spreads in all directions through the dust particles, free water molecules and the molecules of the gases present in the atmosphere. This is called the scattering of light. Or in other words, we can say it is the […]
High-energy states Degenerate matter Under extremely high pressure, as in the cores of dead stars, ordinary matter undergoes a transition to a series of exotic states of matter collectively known as degenerate matter, these are supported mainly by quantum mechanical effects. “degenerate” refers to two states that have identical energy and are thus interchangeable. It […]
Reflection of Light The returning light from the surface of an object when the light is incident on it is called reflection of light. Or in other words, we can say it is the phenomenon of bouncing back light into the same medium by the smooth surface. Examples include a reflection by a plane mirror, glowing […]
The Voyager mission consist of two spacecrafts: Voyager 1 and Voyager 2. Voyager 2 was launched before voyager 1 on August 20 1977 from Florida abroad a Titan-centaur rocket. Voyager 1 was launched on September 5 1977 from Florida abroad a Titan-centaur rocket but it was send on a faster trajectory. Because of its high […]
