Physics

4vir4ik [10]3 years ago
4 0

Explanation:

The image distance gives the position of image formed by a lens. It also shows how far the image is formed form the pole of the lens. There is a relationship between the object distance, object distance and the focal length of the lens. It is given by :

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

Where

v is the image distance

u is the object distance

f is the focal length of the lens

The ratio of image distance to the object distance is called the magnification of the lens. It is given by :

m=\dfrac{v}{u}

Magnification of lens is also defined as the ratio of the height of the image to the height of the object. It is given by :

m=\dfrac{h'}{h}

h' is the height of image

h is the height of object

The magnification of a lens shows that how many times the image is magnified. If the magnification of a lens is more than 1, it shows that the image is greater than the object and if it is less than 1, it shows the image is smaller than the object.

A thin soap bubble of index of refraction 1.33 is viewed with light of wavelength 550.0nm and appears very bright. Predict a pos
faust18 [17]

Answer:

The possible thickness of the soap bubble = 1.034\times 10^{-7}\ m.

Explanation:

<u>Given:</u>

  • Refractive index of the soap bubble, \mu=1.33.
  • Wavelength of the light taken, \lambda = 550.0\ nm = 550.0\times 10^{-9}\ m.

Let the thickness of the soap bubble be t.

It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.

For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:

2\mu t=\left ( m+\dfrac 12 \right )\lambda.

where m is the order of constructive interference.

Since the soap bubble is appearing very bright, the order should be 0, as 0^{th} order interference has maximum intensity.

Thus,

2\mu t=\left (0+\dfrac 12\right )\lambda\\t=\dfrac{\lambda}{4\mu}\\\ \ = \dfrac{550\times 10^{-9}}{4\times 1.33}\\\ \ = 1.034\times 10^{-7}\ m.

It is the possible thickness of the soap bubble.

What makes science different from other fields of knowledge like art or philosophy?
makkiz [27]
As opposed to art or philosophy, science is an objective phenomenon. It deals with something which is verifiable, meaning that it can be tested, and it is based on facts, which are true and can be proven. On the other hand, art is highly subjective, which means that it can be interpreted in many different ways. Science is more concrete and testable, whereas art and philosophy lie in the domain of the abstract.

Drag each circle to the correct location on the image. Each circle can be used more than once, but not all circles will be used.

Based on the given information, the type of boundaries these two new plates would share with each other and the Arabian Plate are divergent boundaries.

<h3>Who are geologists?</h3>

A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other planets.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.

There are 3 types of boundaries.

At convergent boundaries, the two tectonic plates comes closer to each other.

At divergent boundaries,  the plates move away from each other.

At transform boundaries,  the plates are moving parallel to their boundary.

Based on this, all boundaries will be divergent boundaries.
