Question

Explain how to read the color spectrum a spectrograph gives us.

A. The color spectrum is interpreted by analyzing the sequence of colors in order from red to violet, known as the rainbow, and identifying the wavelengths associated with each color.

B. The color spectrum is read by looking for patterns of intensity and brightness in different color regions.

C. The color spectrum is determined by counting the number of colors visible in the spectrograph image.

D. The color spectrum is understood by examining the shape of the spectrograph's lines and their positions on the scale.

Answer 1

The color spectrum from a spectrograph is read by analyzing the sequence of colors in order from red to violet, known as the rainbow, and identifying the wavelengths associated with each color.

Step-by-step explanation:

The color spectrum from a spectrograph is read by analyzing the sequence of colors in order from red to violet, known as the rainbow, and identifying the wavelengths associated with each color. When white light is dispersed according to different wavelengths, it creates a rainbow of colors. Each color represents a different frequency of visible light. A spectrograph can separate the different colors and allow astronomers to analyze the light and identify the chemical elements present.
