**Pre-lab Questions**
1. **How does the EM spectrum help us find out what stars are made of?**
The electromagnetic (EM) spectrum helps us determine the composition of stars and other astronomical objects by analyzing the light they emit. When light from a star passes through a prism or is observed through a spectrometer, it creates a spectrum that shows various wavelengths of light. Each element emits or absorbs light at characteristic wavelengths, resulting in unique patterns of lines (spectral lines) within the spectrum. By comparing the observed spectral lines to known wavelengths associated with specific elements, scientists can identify the elements present in the star's atmosphere, allowing us to infer its composition, temperature, density, mass, distance, luminosity, and relative motion.
2. **Why do you think it is important to use different types of technology when studying space?**
Using different types of technology is essential when studying space because each technology can observe different aspects of celestial objects across various wavelengths of the electromagnetic spectrum. For example, optical telescopes capture visible light, while radio telescopes detect radio waves, and infrared telescopes observe heat emitted by objects. This multi-wavelength approach allows astronomers to gather a more comprehensive understanding of the physical properties and behaviors of astronomical phenomena. Different technologies can also penetrate different types of cosmic dust and gas, revealing hidden structures and the composition of objects that might be obscured in one wavelength but visible in another. This diversity in technology enhances our overall observations and leads to richer scientific insights.
