Dispersion

Why is the spectrum of light separated into its components of color when white light is directed to a prism?

• Because light reflects off the prism's surface

• The incident white light refracts and separates into its constituent colors

• The white light is absorbed by the prism, separating its colors

• The light speeds up as it moves from air into the denser plastic material

Why is the component of colour in a rainbow can be seen when light passes through a glass prism?

• phenomena of scattering of light

• phenomena of dispersion of light

• phenomena of reflection of light

• phenomena of diffraction of light

Why is the spectrum of light seperated into its components of colour when white light is directed to a prism?

• The different colours in the white light bend away from the normal line at different angles when entering prism

• The different colours in the white light bend towards the normal line at different angles when entering prism

• The different colours in the white light bend away from the normal at same speed to each other when entering prism

• The different colours in the white light bend towards the normal at same speed to each other when entering prism

Look at the diagram given. This is the first prism. What happen if A SECOND inverted prism is placed behind the first prism?

• the various colours pass through it and form brighter spectrum

• the various colours pass through it and form a white light back

• the various colours pass through it and form an opposite spectrum colours

• nothing will happen

The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a specific point in time -

Dandelions and other plants with wind-dispersed seeds spread widely and germinate where they land. Which type of dispersion does this describe?

• Clumped dispersion

• Uniform dispersion

• Random dispersion

The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time -

Animals that maintain defined territories, such as nesting penguins, also exhibit which type of dispersion?

• Clumped dispersion

• Uniform dispersion

• Random dispersion

The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a specific point in time -

Animals that maintain a clear territory, such as nesting penguins, exhibit which type of dispersion?

• Clumped dispersion

• Uniform dispersion

• Random dispersion

The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time -

Dandelions and other plants that have wind-dispersed seeds spread widely and sprout where they happen to fall describes which type of dispersion?

• Clumped dispersion

• Uniform dispersion

• Random dispersion

Students conducted an experiment to see how different lights behave when pointed at a prism. They used a white light and a red laser light.

What best explains why the red light does not change color when refracted in a prism, while the white light makes a rainbow?

• Red light is reflected by the prism

• White light cannot bend.

• White light is made of all other colors of light.

• Red light is absorbed by the prism.

This is the example of dispersion of light

• sky looks bright orange in the evening

• shadow

• Pool seems shallower

• rainbow
