Supporting answer: Diffraction
Diffraction of light is the phenomenon where the bending of light happens around corners such that it spreads out and illuminates areas where the formation of shadow is expected.
The diffraction of light is divided into two types:
- Fresnel diffraction: Here the division of light is from a point source and incident and diffracted wavelengths are spherical
- Fraunhoffer diffraction: Here the division of light is from a point source or multiple source and incident and diffracted wavelengths are parallel.
Here diffraction grating, is defined as an optical element that divides the light into various wavelengths.
The formula for diffraction is: dsinФ=nλ
where, d is the distance between the slits, Ф is the diffracting angle, n is the order number and λ is the wavelength.
Given, grating is 2090 grooves per centimeter for n=1,
d=n/λ
Then,
![d=\frac{1*10^{-2} }{2090} \\d=4.78*10^{-6}m](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B1%2A10%5E%7B-2%7D%20%7D%7B2090%7D%20%5C%5Cd%3D4.78%2A10%5E%7B-6%7Dm)
Therefore,
dsinФ=nλ
sinФ=nλ/d
![=\frac{1*640*10^{-9} }{4.78*10^{-6} } \\=133.89*10^{-3} \\=0.1338](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%2A640%2A10%5E%7B-9%7D%20%7D%7B4.78%2A10%5E%7B-6%7D%20%7D%20%5C%5C%3D133.89%2A10%5E%7B-3%7D%20%5C%5C%3D0.1338)
Ф=
![=sin^{-1} (0.1338)\\=7.68](https://tex.z-dn.net/?f=%3Dsin%5E%7B-1%7D%20%280.1338%29%5C%5C%3D7.68)
Therefore, the red light appears at an angle of 7.68

Answer:
1.51783893986
Explanation:
One kilogram is equal to 9.81 Newtons
You have 14.89N, divide this by 9.81 and u get the mass in KG
so u do 14.89/9.81 = 1.51783893986 or 1.52kg (2dp)
Answer:
1) Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.

Answer:
One of the leading theories of hot-Jupiter formation holds that gas giants in distant orbits become hot Jupiters when the gravitational influences from nearby stars or planets drive them into closer orbits. They formed as gas giants beyond the frost line and then migrated inwards.
Explanation:
In the migration hypothesis, a hot Jupiter forms beyond the frost line, from rock, ice, and gases via the core accretion method of planetary formation. The planet then migrates inwards to the star where it eventually forms a stable orbit. The planet may have migrated inward smoothly via type II orbital migration.
Hot-Jupiters are heated gas giant planets that are very close to their stars, just a few million miles distant and orbiting their stellar hosts in just a few days. The reason why there isn't one in our Solar System is down to its formation. All gas giants form far from their star but then some migrate inwards.
Hot-Jupiters will just happen to transit about 10% (that is, since orbital planes) this is consistent with the rate expected from geometry of . The actual frequencies of hot Jupiters around normal stars is surprisingly hard to figure out.
