Because light also travels at a speed, by the time you see it, (depending on how far away it is) it probably happened a few or many years ago.
The collimator present in a spectrometer convert the rays from the source to parallel rays .Telescope is used to watch the parallel rays which means for the telescope the object is located at infinity.so that we use telescope.
What did you observe! This is not a question we can answer as we were not present when the salt was added.
This could be caused by a number of issues. Beginning with the simplest, there could be an optical blockage somewhere, either in the form of a lens cap or a non refracting object between your target and your eye, Since the 114 is a reflecting telescope, there may be an issue with the mirror's collimation. This would make it difficult to focus on anything and induce coma on your targets. Simple google Collimating A Reflecting Telescope to learn how to fix this. Finally, you could have an inferior eyepiece that is plagued with few coatings and many aberrations. This would present a rather fuzzy and clouded image. Make sure to check all optics for anything that may need to be cleaned and adjusted, especially if you just bought it.
To describe the orange liquid's properties without altering it, I would first visually observe its color, clarity, and any particulates present. Then, I would measure its density by determining its mass and volume, and assess its viscosity by observing how it flows. Additionally, I would use a smell test to identify any distinct odors, and if safe, I might also use pH paper to gauge its acidity or alkalinity.
HST's Near-Infrared Camera/Multi-Object Spectrometer(NICMOS), installed on Servicing Mission 2 in 1997, and repaired during Servicing Mission 3A, was installed specifically to observe the infrared spectrum.The James Webb Space Telescope (formerly the Next Generation Space Telescope), currently in final design reviews (the final step prior to manufacturing and testing) is designed as an outer orbit (past the Moon) infrared space telescope. The technology involved in such a device has caused a few delays, as the temperatures at that distance are much colder than in Earth orbit, and present different challenges for a device that must respond to precise commands, as well as one that can't be repaired.

People should observe to gain a deeper understanding of the world around them, enhancing their awareness and appreciation of different perspectives. Observation fosters critical thinking and allows individuals to learn from their environment and experiences. It also promotes mindfulness, encouraging a more present and engaged way of living. Ultimately, observing enriches personal growth and encourages meaningful connections with others.
Because light takes time to travel from one place to another.You don't need a telescope to observe the past.When you look at the moon, the light that enters your eyes left the moonabout 1.28 seconds ago.When you look at the sun, the light that enters your eyes left the sunabout 81/3minutes ago.When you look at the nearest star outside the solar system, the light thatenters your eyes left the star more than 4 years ago.You see every other star as it used to be, even farther back in the past than that.When you look at the North Star (Polaris), the light that enters your eyes left itabout 323 years ago. If the North Star exploded on the day George Washingtonwas born, we'll see the explosion in 2055 .When you look at the refrigerator, 10 feet away at the other end of the kitchen,you're seeing it as it was about 0.0000000102 second ago.
if you give a clock to the Chinese as a present, it means you wish to attend their funeral
You can determine if camphor is still present by observing the IR data. If there is a peak in the region of 1715 cm−1, then camphor is present.
