Answer:

The prism refracts the light, breaking it into its different wavelengths and making a rainbow.

Explanation:

A prism is a clear glass pyramid with identical faces. It is a special optical device.

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

White light is a type of light that comprises of all the colours that makes up the visible spectrum (ROYGBIV). It's the most common light humans interact with on a daily basis.

When white light is shined on a prism, the prism refracts the light, breaking it into its different wavelengths and making a rainbow. Thus, this lead to a phenomenon known as dispersion, which typically involves the separation of light into its full spectrum with respect to wavelength. Also, refraction causes dispersion in rainbows.

According to Sir Isaac Newton, refraction causes dispersion i.e the speration of white lights into its various wavelength.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. A

Given:

The solution decreased by $\dfrac{9}{8}$ ounces every hour for 5 hours.

Remaining solution at the end of the experiment = $\dfrac{99}{8}$ ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by $\dfrac{9}{8}$ ounces every hour for 5 hours.

Total decreased amount $=\dfrac{9}{8}\times 5$

$=\dfrac{45}{8}$

Initial amount = Remining amount + Decreased amount of solution.

$x=\dfrac{99}{8}+\dfrac{45}{8}$

$x=\dfrac{99+45}{8}$

$x=\dfrac{144}{8}$

$x=18$

Therefore, the initial amount of solution is 18 ounces.

Two scientists produce two different cladograms for the same group of organisms. Explain how the differences are possible.

S_A_V [24]

Answer:

Due to different grouping style

Explanation:

There are two modes of classifying an organism due to which two different cladogram are produced-

A) When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.

B) In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.
