Which describe the study of spectroscopy? Select the two correct answers.(1 point)
interaction of light and atoms
interaction of light and atoms
reflection of light by Earth
reflection of light by Earth
emission and absorption of light
emission and absorption of light
the number of galaxies
the number of galaxies
The correct answers are:
1. Interaction of light and atoms
2. Emission and absorption of light
To determine the correct answers, we need to understand what spectroscopy is. Spectroscopy is the study of the interaction between light and matter. It involves the analysis of how different types of atoms and molecules interact with light, specifically in terms of emission and absorption.
Option 1 is correct because spectroscopy focuses on understanding how light interacts with atoms. By analyzing the spectrum of light emitted or absorbed by atoms, scientists can gain valuable information about their properties and behavior.
Option 2 is also correct because spectroscopy involves both the emission and absorption of light. When atoms absorb light, they can transition to higher energy states, and when they emit light, they return to lower energy states. This light emission and absorption is the basis for many spectroscopic techniques.
Options 3 and 4 are incorrect because they are unrelated to the study of spectroscopy. Spectroscopy specifically deals with the interaction of light and matter, not with the reflection of light by Earth or the number of galaxies.
