When blue shift occurs, how does the wavelength of light that we see change?

Answers

Answer 1
The doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the detector.
Doppler effect in light is actually a relativistic effect (caused due to relativistic time dilaton and can be explained by special theory of relativity) but somewhat similar to the one which happens in sound waves. This effect has nothing to do with the bending in spacetime.
When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector (think of a wave being stretched), as a result the frequency decreases (since, speed of light is constant in all frames). Due to this decrease in frequency the light emitted from the source appears more red (since red color is on low frequency side in the electromagnetic spectrum) compared to the situation when source was at rest.
Vice versa for the source moving towards the detector
This shift in frequency is also known as doppler shift.
The shift in frequency when the source is moving away is known as redshift and the opposite one is known as blueshift.

Bearings are angles, measured clockwise from north.

To measure a bearing, we must first know which direction is north.

This north direction is usually provided in the maths exam question. We then measure the required angle in a clockwise direction. All bearings need to be given in three figures, so if the angle measured is less than 100100 degrees, we must start the three-figure bearing with a zero.

The automobile gave people more personal freedom and access to jobs and services. It led to development of better roads and transportation. Industries and new jobs developed to supply the demand for automobile parts and fuel. These included petroleum and gasoline, rubber, and then plastics.

Explanation:

Large industries, such as the automobile industry provide job opportunities for civilians, so cities and towns may form around factories where products are needing to be produced. They also give civilians more of an advantage for migration and travel, allowing people to move more easily from place to place and discover and develop new cities and societies

How was Louis XIV treating his people BEFORE the Revolution?

Answers

Answer: Louis was the son of Louis XIII and his Spanish queen, Anne of Austria. He succeeded his father on May 14, 1643. At the age of four years and eight months, he was, according to the laws of the kingdom, not only the master but the owner of the bodies and property of 19 million subjects. Although he was saluted as “a visible divinity,” he was, nonetheless, a neglected child given over to the care of servants. He once narrowly escaped drowning in a pond because no one was watching him. Anne of Austria, who was to blame for this negligence, inspired him with a lasting fear of “crimes committed against God."

Before the French Revolution, Louis XIV treated people horribly and always looked to consolidate his own powers.

King Louis XIV, also known as the Sun King, ruled as an absolute monarch with a centralized and authoritative regime. He implemented policies that aimed to consolidate his power and maintain control over his subjects.

While he was known for his grandeur and lavish court at Versailles, the majority of the population faced harsh conditions. The common people endured heavy taxation to fund the king's extravagant lifestyle and military campaigns.

Additionally, Louis XIV restricted individual freedoms and suppressed dissent, leading to limited political representation and a lack of social mobility. The nobility enjoyed privileges and exemptions, further exacerbating social inequality.

Thus,  Louis XIV's rule was characterized by a highly hierarchical society and a vast power imbalance between the monarchy and the general population.

Imagine that the rectangle is rotated counterclockwise. Make a conjecture as to which properties of a figure stay the same after the rotation

Answers

The rotation defined withinside the problem is referred to as a rigid transformation, which refers to all transformation that does not alternate the form or length of the object, like in this case.

Which form is a rectangle?

A rectangle is a kind of quadrilateral, whose contrary aspects are the same and parallel. It is a four-sided polygon that has 4 angles, same to ninety degrees. A rectangle is a two-dimensional form.

Basically, the rectangle after the counterclockwise rotation continues its facet lengths, and its angle, but modifies its vertices, that is, its coordinates without changing its dimension. This conjecture englobes all critical traits of the rectangle.

Hence, the residences that continue to be the same after rotation are their angles, aspects, and form.
