(Solidification) You are performing a double slit experiment very similar to the one from DLby shining a laser on two narrow sli

ts spaced 7.5 × 10-5meters apart. However, by placing a piece of crystal in one of the slits, you are able to make it so that the rays of light that travel through the two slits are πout of phasewith each other (that is to say,Δφ!=휋).If you observe that on a screen placed 4meters from the two slits that the distance between the bright spot closest to the center of the interference pattern and the center of the pattern is 1.5 cm, what is the wavelength of the laser? (Just as in DL, you may use the small angle approximation sinθ ≈ θ ≈ tanθ.)

Answer:

The wavelength of the laser, λ = 5.625 * 10⁻⁷ m

Explanation:

Separation of the narrow slits, d = 7.5 * 10⁻⁵ m

The distance between the screen and the two slits, d = 4m

The distance between the bright spot and the center of the pattern, Y = 1.5 cm

Y = 1.5 * 10⁻² m

To calculate the wavelength, λ, of the laser we will use the relationship:

Y = \frac{\lambda L}{2d} \\1.5 * 10^{-2}  = \frac{\lambda * 4}{2*7.5*10^{-5} }\\\lambda = \frac{1.5 * 10^{-2} * 15 * 10^{-5} }{4}

λ = 5.625 * 10⁻⁷ m

In handball, who is the only player allowed in the goalie area?
lidiya [134]

Answer:

Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

Atoms that are bonded together to form a new material with new<br> properties and characteristics. .
mihalych1998 [28]

Answer:

Explanation:

Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

Identify how the energy flows up through the ecosystem. Describe how decomposers help to cycle matter in an ecosystem and their
NNADVOKAT [17]

Answer:

Decomposers are organisms that break down dead or decaying organisms, they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.
