Describe how the wavelengths of energy is organized on the spectrum
Answer:
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. ... The spectrum of waves is divided into sections based on wavelength.
Explanation:
hope that helps!....
Answer:
When the frequency increases the wavelength decreases and vice versa. There are different sections: radio waves, micro waves, infrared rays, visible light, ultraviolet waves, x-rays, and gamma waves. You can see colors because of visible light.

How are the groups organized in the periodic table? What do all the elements in a group have in common?
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
The groups in periodic table are vertical columns in which elements with similar properties and same number of valence electrons are classified together.
What are groups in periodic table ?In periodic table, all elements are classified into different periods and groups. The vertical columns in the table is called groups and the horizontal rows are called periods.
The elements in a group have same number of valence electrons and similar chemical and physical properties. For example lithium and sodium are first group elements and they show similarity in properties.
There are 18 groups and 7 periods in periodic table. The first two groups are pure metals. Groups from 3-12 are called transition metals. 13 to 18 group elements are nonmetals.

At the end of the school day, the teacher gives each student a compass. She explains that a compass is made of a small piece of metal called a needle. She also told students that the Earth has a magnetic force around it. She asked students to use what they've learned about electric and magnetic forces to explain why a compass always points north.
Which of the following is the best explanation of why a compass points north?
A.The needle of the compass is likely pulled towards the north because the needle and north area of the Earth are both positively charged, causing an attraction.
B.Since the Earth has a magnetic force, it must attract one end of the needle. The needle likely has an electric force that is affected by the magnetic force of the Earth.
C.Since the Earth has a magnetic force, it must attract one end of the needle. The needle is likely magnetic and has opposite charges on each end
.D.The Earth's magnetic force causes metals, like the needle of a compass, to point north because of the electric force in the needle. They likely repel each other.
