what is the diffraction angle in degrees for a setup using a 6,393 angstrom slit with a minima of order 28 and a wavelength of 22 nm?
Diffraction depends on the ratio of wavelength to linear dimension of obstacles in the optical path.
What is a diffraction angle?
Diffraction depends on the ratio of wavelength to linear dimension of obstacles in the optical path. The smaller the value of this ratio, the less diffraction. As an example, consider Fraunhofer diffraction from a single slit. where the width of the slot is the linear dimension of the obstacle. We call the slit an obstacle because only a limited portion of the wavefront in the plane of incidence can pass through it. In fact, we define diffraction as the effect caused by a finite portion of the wavefront.
For a single slit, finding the angular distance between the main maxima and the first minima gives a rough idea of how much diffraction is occurring.
What is wavelength?
Wavelength is the distance between identical points (adjacent peaks) in adjacent cycles of a waveform signal propagating in space or along a line. For wireless systems, this length is usually specified in meters (m), centimeters (cm), or millimeters (mm). For infrared (IR), visible light, ultraviolet (UV), and gamma rays (γ), wavelengths are more commonly specified in nanometers (nm), with units of 10-9 m or Angstroms (Å). , which is in units of 10-10 m.

What is orbital periods?An orbital period is the time it takes for a given astronomical object to orbit another object. In astronomy, it usually applies to planets or asteroids orbiting the sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. Changes in the orbital period can be explained by the evolution of the mass asymmetry to symmetry (symmetry of the binary system). Decreasing and increasing orbital periods are predicted to be related to the non-overlap and overlap of the binary in its symmetrisation respectively. Orbital decay is the gradual decrease in the distance between two orbiting bodies at their point of closest approach over several orbital periods. These orbiting bodies can be a planet and its satellite, a star and any object orbiting it, or parts of some binary system.Therefore,
distance of first satellite = 48,000 Km

In physics, a force is a power that can change the motion of an item. A force can purpose an object with mass to alternate its pace. Pressure also can be described intuitively as a push or a pull. A force has both value and path, making it a vector quantity.
Pressure is a push or a pull and it affects our daily lives because, without force, people might not be capable of opening and near stuff or lifting up their arms or legs.
Variety of Forces :
* Muscular Forces, muscular tissues feature to produce an ensuing force which is referred to as 'muscular force'.
* Frictional Forces, while an item modifications its national motion, 'frictional pressure' acts upon it.
* Carried out pressure.
* Tension force.
* Spring force.

During the formation of the Solar System, smaller particles in the solar nebula combined to form planetesimals, some of which provided the building blocks for planets. The majority of planetesimals did not become planets, however, and some of them remain in the Solar System today as debris left over from the time of planet formation. Asteroids are a special class of planetesimals that orbit around the Sun. Study the distribution of known asteroids shown in this figure, and choose all of the statements below that match your observations. Choose one or more: A. All of the asteroids exist in a region between Jupiter and Mars B. Some asteroids cross Earth's orbit as they orbit around the Sun C. The majority of asteroids exist in a region between Jupiter and MarsD. Asteroids have been discovered as tar out as PlutoE. There are dumps of asteroids that existat particular spots in Jupiter's orbit IF The majority of asteroldsedstinside of Mars orbit EG Asteroids are randomly distributed throughout the Solar System
Some meteorites cross Solar system as they revolve around the Sun, while others form clusters at certain locations in Jupiter's orbit. The bulk of asteroids are located in the space between Jupiter the Mars.
Where are the asteroids?Half way between Venus and Mars' orbits, the Solar System's asteroid belt seems to be a torus-shaped zone. It comprises a large number of asteroids or minor planets, which are rocky bodies with variable shapes and sizes that are significantly smaller than planets.
What factors lead to asteroids?Asteroids are remains of the solar system's creation, which occurred around billion years ago. Early on, Jupiter's creation prevented additional planetary bodies from growing in the space between Asteroid belts, leading the small particles that did exist to collide with one another and disintegrate into the asteroids we know today.
