4) A light beam shines through a thin slit and illuminates a distant screen. The central bright fringe on the screen is 1.00 cm

wide, as measured between the dark fringes that border it on either side. Which of the following actions would decrease the width of the central bright fringe? (There may be more than one correct choice.) A) increase the wavelength of the light B) decrease the wavelength of the light C) increase the width of the slit D) decrease the width of the slit E) put the apparatus all under water

The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.

<h3>Wavelength of the light</h3>

The wavelength of the light is determined using the following formulas;

\lambda = d(\frac{y}{D} )

where;

  • λ is wavelength
  • d is width of the slit
  • D is the distance of the screen
  • y is distance between the central bright fringe and dark fringe
<h3>Actions that would decrease the width of the central bright</h3>

y = (λD) / (d)

  • Decrease in the wavelength of the light
  • Increase in the width of the slit

Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.

How does radiation transfer thermal energy from the Sun to Earth?
Svetradugi [14.3K]

Answer:

The thermal energy is carried by electromagnetic waves

Explanation:

There are three types of transfer of heat (thermal energy):

- Conduction: conduction occurs when two objects/two substances are in contact with each other. The heat is transferred from the hotter object to the colder object by the collisions between the molecules of the two mediums.

- Convection: convection occurs when a fluid is heated by an external source of heat. The part of the fluid closer to the heat source gets warmer, therefore it becomes less dense and it rises, and it is replaced by the colder part of the fluid, which is colder. Then, this part of fluid is heated as well, so it gets warmer, it rises, etc.. in a cycle.

- Radiation: radiation occurs when thermal energy is carried by electromagnetic waves. Since electromagnetic waves do not need a medium to propagate, this is the only method of heat transfer that can occur through a vacuum (so, in space as well).

Indeed, the Sun emits a lot of electromagnetic radiation, which travels through space and eventually reaches the Earth, heating it.

Electricity may be categorized as static or current. how are these two types of energy different
arlik [135]
Hello!

Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.

Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)

What is the difference between unicellular and multicellular organisms?
bija089 [108]
Multicellular organisms<span> can be much larger and more complex. This is because the cells of the </span>organism<span> have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.

</span><span>A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.

Earlier we discussed the concept of isostasy, where lower density rocks rise higher than higher density rocks. How is the variat
Elena L [17]

The variation of water depth at spreading centers (ridges) controlled by isostasy  as convective cooling cools the rocks much more effectively the than heat conduction.

<h3>What is convective heat transfer?</h3>

When heat transfer takes place between the two fluids in direct or indirect contact.

The lithosphere cools when it moves away from the ridge axis by sea floor spreading. The cooler rocks have low density, so the sea floor gets deeper as the lithosphere gets more dense.

Thus, the convective cooling cools the rocks much more effectively the than heat conduction.
