Observing Stars Essay

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

Gamma: this is a ray of electric radiations this is a part of electromagnetic spectrum. In the high energy and low wave frequency part. When ionising gamma rays pass through gamma because they are weak, travel through space and vacuum.

We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.

3. Solar Flares: these are ejections of large volumes of gas. They can sometimes head our way causing radio interference and auroras.

Light is electromagnetic radiation, energy shown as a wave or a particle, that can be visually perceived as radiant energy.1 Light is measured by the wavelength and frequency. A wavelength is the distance from any point on one wave to the same point on the next wave and shown by lambda, λ.2 The different types of light begins with gamma rays and proceed to radio waves when increasing wavelengths are compared. Frequency is the number of crests per second and is expressed in hertz and shown as v. The pattern associated with light is indirectly related to the wavelength. The variability of light starting with gamma rays and ending with radio waves is connected by decreasing frequency. Frequency is independent of the wavelength and are both

The sun produces electromagnetic radiation of all wavelengths, with the visible spectrum being the most intense wavelength range produced as the radiation peaks at this area of the EM spectrum. The Earth’s atmosphere absorbs most of this radiation but light and radio waves are able to penetrate the atmosphere, as well as short wavelength infrared rays and long wavelength microwaves. X-rays and gamma rays are absorbed by the Earth’s upper atmosphere.

The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation, the most prevalent type of telescope is the optical telescope which collects light, however there are other kinds of telescopes which collect UV and X -Rays. Optical telescopes use lenses to redirect light to a specified point. Different lenses are used for different magnifications of celestial objects. This essay will be mainly discussing optical telescopes.

Radio telescopes are similar to optical telescopes however they measure the radio frequency portion of the electromagnetic spectrum rather than the visible portion. We use radio telescopes to study naturally occurring radio wavelength light from stars, galaxies, black holes and other astronomical objects. In order to locate gravitational waves we are looking for oscillations in the images we see, as gravitational waves will bend light such as radio waves in alternating directions.

While radio astronomers are able to observe at any time of day and night, optical astronomers are mainly limited to observing at night. One would think that both radio astronomers and optical astronomers would be able to study at the same and all the time due to both of them studying the universe thru light waves, yet still optical astronomers can not typically study during the day. Although both study thru light waves. radio astronomers study using radio waves and optical astronomers usually use light in the visible light spectrum. Therefore, while radio waves are observable during the day and night, light in the visible light spectrum is variable on what is visible to humans. During the day, due to the absorption of molecules, the sky is

Electromagnetic radiation are electromagnetic waves, or photons, that are emitted by astronomical bodies and travel in all frequencies (Auger, 1964). Particle radiation, on the other hand, are charged particles traveling at high speeds, protons, and even nuclei of other heavier elements. These particles tend to travel near the speed of light, so fast that their electrons are completely striped from

Talia Hale was sitting down at the dinner table waiting for her kids to join her. Though this issue only affected two of them, she felt Laura should also be there when they discussed it. Hopefully to keep the other from being too outraged with her decision. She knew neither would be happy at finding out they had to marry, and soon. But it was the fate of all royalty to ensure their people were happy and provided for. Her people were not at the moment and she needed to fix that.

According to an online database, Radio waves is a certain type of electromagnetic radiation that contains “frequency of between 300 GHz to as low as 3 kHz” (“Radio waves”, 2014). [Definition]. a. Netting (2007) states that radio waves have the longest wavelengths in the electromagnetic spectrum. b. Dictionary.com defines Electromagnetic radiation as electric and magnetic energy waves which move together at the speed of light (2014).

A wave of light is made by the colors visible in the spectrum. Each color of light has a different wave length. The amplitude of a wave is the part of the wave that determines its distance and length. A wave’s highest point is the crust and its lowest point is the through. The frequency of a wave tells the amount of waves that go through a specific object.

By looking at the different wavelengths or the spectrum of light from a celestial object, you can tell many of its properties and features. To do this, the Hubble Telescope is equipped with various scientific instruments. Each instrument used

Among these are star maps, planispheres, filters, and various photographical devices. Starting with planispheres and star maps, these are used to aid in manual telescope operation. The last telescope I discussed was a reflector telescope that used an Alt-Az mount, meaning locating celestial objects relies fully on the operator’s ability to use maps and star guides so get a lay of the land, or sky for this matter. Looking at the sky isn’t near as easy as it may sound. Much like how the Earth is covered in seventy percent water, the night sky is mainly stars. Without proper synchronization with the night sky, you can be off in your observations by a long shot. Planispheres come in different editions depending on which hemisphere you reside in. Stars positioning and celestial objects available for observation can also change depending on your latitude, time of day, and also time of
