Question

1. what caused the missing colors on the electromagnetic spectrum for the sun? (1 point)

they were absorbed when leaving the sun.
those colors are not produced by the sun.
the heat of the sun vaporizes those colors.
they were emitted when leaving the sun.

1. which statement about the black absorption lines is true? (1 point)

all elements have identical patterns and number of lines.
each element has its own unique pattern and number of lines.
the absorption lines are all at the same location and have the same thickness.
every element has the same number of absorption lines.

1. what do the absorption lines tell us about a star? (1 point)

the temperature of the star

Explanation:

• Question 2: When light leaves the sun, certain elements in the sun's atmosphere absorb specific wavelengths of light. These absorbed wavelengths correspond to the "missing colors" on the electromagnetic spectrum.
• Question 3: Each element has its own unique set of energy levels. When electrons in an element transition between these energy levels, they absorb or emit specific wavelengths of light. This leads to each element having a unique pattern and number of absorption lines.
• Question 4: The absorption lines in a star's spectrum can tell us about the elements present in the star. Different elements have different absorption line patterns.

Answer:

1. They were absorbed when leaving the sun.
2. Each element has its own unique pattern and number of lines.
3. The elements present in the star.
