A light wave encounters a partial physical barrier, such as a wall with a hole in it. What is MOST LIKELY to occur?

2 answers:

8 0

The light will be diffracted.
diffraction - bending of a wave in a homogeneous medium around obstacles or through a narrow opening.

hope this helps :)

Most likely, the light wave will be absorbed by the wall. Without any information as to the size and color of the wall, the location and size of the hole, or the location of the light wave, this is a generalized probability problem. For all of the places the light could be, it's more likely that it hits the wall than the hole (if the hole is less than 50% of the area of the wall).

A screen is separated from a double-slit source by a distance L. When light of wavelength 563 nm is incident on the double slit,

Andrew [12]

Answer:

β 2 = 0.02575 mm

Explanation:

given data

wavelength = 563 nm

separation distance between adjacent bright fringes = 0.0290 mm

wavelength = 500 nm

solution

we get here separation distance between adjacent bright fringes that is express as

β = $\frac{\lambda D }{d}$ ..................................1

here D is distance from plane of slit to screen

and d is slit sepation that is constant

$\frac{\beta 1}{\beta 2} = \frac{\lambda 1}{\lambda 2}$

β 2 = $\frac{500}{563} \times 0.0290$

β 2 = 0.02575 mm

Measure the distance from the drop point in Brazil to the drop point in Angola. Use that number in your calculation. Given that

klemol [59]

To develop this point we will start by finding the approximate coordinates of the points that were connected at the time of the Pangaea between Brazil and Angola. These coordinates are presented below.

1 . Brazil - Latitude: 18 0 07’ 55.56” S Longitude: 39 0 35’ 14.50” W 2.

Angola - Latitude: 9 0 08’ 50.02” S Longitude: 13 0 02’ 32.11” E

Using a tool for calculating distances between these two points we will notice that its distance is 576,155,570.12 cm

Applying the equation given in the statement we will have to,

$v = \frac{x}{t} \rightarrow v = Velocity, x = Distance, t = Time$

200,000,000 years have passed and the movement was previously found, so the speed of travel is,

$v = \frac{576,155,570.12cm}{200.000.000 years}$

$v = 2.88 cm/year$

Therefore the velocity is 2.88 cm per year.
