Plane mirrors and CONVEX mirrors will always produce an upright image. A concave mirror will only produce an upright image if the object is LOCATED in front of the FOCAL POINT.

the phenomena in this picture is dispersion. when a beam of white light travels through a prism it will disperse to its SEVEN unique colours NAMELY violet, Indigo, blue, green, yellow, orange and RED. also known as {VIBGYOR}.

The X is a beam of white light.

The Y PART is Triangular Prism.

The Z part is VIBGYOR colours.

Additional information :

Global integration through trade and finance is the defining feature of today's international economic order. As mature industrial economies and emerging market economies become more integrated and interdependent, countries that play a key role in the global supply chain increasingly shape the world economy and influence its dynamics. How is the world economy changing? This article argues that a multipolar structure is an accurate description of the pattern in which the world economy is organized and POWER is distributed among players. Power is now more diffused, but not equally distributed; new players have increased their capacity for ACTION, but not necessarily their influence. The balance remains tilted in favour of the old poles, with the United States in the strongest, albeit LESS dominant, position. In particular, there is a misalignment between the new poles' role in the global economy and their ability, and willingness, to influence institutions and participate in rule-setting. This is where the major source of potential TENSION and conflict lies in today's economic order. The combination of global financial markets and national politics has created a lopsided system where political arrangements are still based on the sovereignty of states and where the development of international institutions that could promote collective goods has not kept pace with the development of markets. Looming changes and fear of systemic collapse, especially in view of the current economic turmoil that has the potential to weaken global growth and impose huge strains on the international order, may spur action. However, WHETHER this will trigger renewed efforts to rethink existing arrangements, improve global governance and strengthen the rules-based framework that underpins the global order remains an open question.

Answer:

Know how black hole works

There are two theories:-

1.A black hole is a region of spacetime where gravity is so strong that nothing—no PARTICLES or even electromagnetic radiation such as light—can escape from it.[1] The theory of general relativity predicts that a SUFFICIENTLY compact mass can deform spacetime to form a black hole.[2][3]

The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, according to general relativity it has no locally detectable features.[4] In many ways, a black hole acts LIKE an ideal black body, as it reflects no light.[5][6] Moreover, quantum field theory in curved spacetime predicts that event horizons EMIT Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe directly.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.[7] The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.

Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar MASSES (M☉) may form. There is consensus that supermassive black holes exist in the centers of most galaxies.

The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. Matter that falls onto a black hole can form an external accretion disk heated by friction, forming quasars, some of the brightest objects in the universe. Stars passing too close to a supermassive black hole can be shred into streamers that shine very brightly before being "swallowed."[8] If there are other stars orbiting a black hole, their orbits can be used to determine the black hole's mass and location. Such observations can be used to exclude possible alternatives such as neutron stars. In this way, astronomers have identified numerous stellar black hole candidates in binary systems, and established that the radio source known as Sagittarius A*, at the core of the Milky Way galaxy, contains a supermassive black hole of about 4.3 million solar masses.

On 11 February 2016, the LIGO Scientific Collaboration and the Virgo collaboration announced the first direct detection of gravitational waves, which also represented the first observation of a black hole merger.[9] As of December 2018, eleven gravitational wave events have been observed that originated from ten merging black holes (along with one binary neutron star merger).[10][11] On 10 April 2019, the first direct image of a black hole and its vicinity was published, following observations made by the Event Horizon Telescope in 2017 of the supermassive black hole in Messier 87's galactic centre

2. White hole is just hypothetical thing.This theory states that what a Black hole eats it comes out of white hole.

Einstein-Rosen Bridges are nothing but wormholes. In short, an Einstein-Rosen bridge is a wormhole. The idea was proposed by an Austrian physicist named Ludwig Flamm who envisioned the existence of an anti-black hole. Flamm believed that a theoretical “white hole” could exist that, unlike a black hole, would occasionally spit stuff out rather than suck it all in.

Answer:

Explanation:

∆ Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail.

∆ Electromagnets USUALLY consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil. The magnetic field DISAPPEARS when the current is turned off.

∆ The magnetic field produced due to current flowing in a coil or a solenoid can be used to magnetise a MATERIAL like soft iron TEMPORARILY. The insulated copper wire is warpped on a soft iron piece. When current is PASSED through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.
