Coherent light with wavelength 608 nm passes through two very narrow slits, and the interference pattern is observed on a screen

Kipish [7]

Answer:

$1.22 \mu m$

Explanation:

In the double-slit interference, light passes through a double slit and produce a pattern of alternating bright and dark fringes on a distant screen. This pattern is due to the combined effect of the diffraction of each slit + the interference of the light coming from the two slits.

The condition to observe a maximum (bright fringe), so costructive interference, in the distant screen, is:

$y=\frac{m\lambda D}{d}$

where:

y is the distance of the m-th maximum from the central fringe

$\lambda$ is the wavelength of the light used

D is the distance of the screen from the slits

d is the separation between the slits

In this problem, we know that:

$\lambda=608 nm=608\cdot 10^{-9}m$ is the wavelength of light used

$D=3.00 m$ is the distance of the screen

$y=4.84 mm = 4.84\cdot 10^{-3} m$ is the distance of the first maximum (first-order bright fringe) from the central pattern, so when

m = 1

Solving for d, we find the separation of the slits:

$d=\frac{m\lambda D}{y}=\frac{(1)(608\cdot 10^{-9})(3.00)}{4.84\cdot 10^{-3}}=3.77\cdot 10^{-4} m$

The first dark fringe on the screen instead is given by the formula

$y'=\frac{(\frac{\lambda'}{2})D}{d}$

where

$\lambda'$ is the wavelength of the new light

Here we want the first dark fringe of the new light to be coincident to the first bright fringe of the previous light, so

$y=4.84\cdot 10^{-3}m$

Therefore, solving for $\lambda'$ ,

$\lambda'=\frac{2y'd}{D}=\frac{2(4.84\cdot 10^{-3})(3.77\cdot 10^{-4})}{3.00}=1.22\cdot 10^{-6} m = 1.22 \mu m$

Work can ____ energy between objects and can cause a change in the form of energy.

STatiana [176]

Answer:

Work can transfer energy between objects and can cause a change in the form of energy.

Explanation:

The best explanation can be done with an example.

Consider an apple of mass m falling from a tree. Initially, the apple is at rest on the tree, at a certain height h above the ground, so it has a form of energy called gravitational potential energy, equal to:

$U=mgh$

where g is the acceleration due to gravity.

As the apple falls, the force of gravity acts on it, and so this force does work on the apple. As a result, the potential energy of the apple is converted into another form of energy, kinetic energy, which is the energy due to the motion of the apple:

$K=\frac{1}{2}mv^2$

where v is the speed of the apple.

Consider another example: a man pushing a box along the floor with a force F. The man is doing work on the box, and this work is equal to

$W=Fd$

where d is the displacement of the box. As a result of this work, some of the chemical energy contained in the muscles of the man is transferred into the box and converted to kinetic energy of the box, which is put in motion and it gains a certain speed v. In particular, if there are no frictional forces involved, the work done by the man is equal to the kinetic energy gained by the box.

Describe how the properties of the compound carbon monoxide (CO) differ from the properties of the elements in the compound.

abruzzese [7]

Answer:

A compound is a pure substance made of two or more elements chemically combined in a set ratio. ... If a different ratio of carbon atoms and oxygen atoms are seen in a formula, you have a different compound. For example, carbon monoxide—a gas produced in car engines—has the formula CO.

Describe how one plays Dr.Dogeball

JulsSmile [24]

•To play Dr. Dodgeball you need to have 2 teams to verse each other.
•Next, select one person from each team to be the doctor (depending on the size of the teams you can have varying amounts of doctors)
•Continue to play dodgeball how you normally would
•When a player gets hit and is “out” they have to sit on the ground and wait for the doctor to “revive them” (this usually requires the doctor dragging,touching, or moving the player that is out to a “revival place” which is usually decided on by the advisor or person in charge.
•Finally, try to get all the doctors and players out from the other team. Get the doctors first, for they cannot revive themselves. Which means the other players are out after they get hit with a ball since the doctors are out. (Some games are played where if all doctors are out the game ends)
Hope this helped! Play on! And plz mark brainliest lol this was long to write :D
