Reflecting Telescope Telescope A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. Today‚ the reflecting telescope is considered as one of the most powerful scientific instruments ever invented. Within a few decades‚ the reflecting telescope was invented‚ which used mirrors. In the 20th

As you saw in Activity 33‚ “From One to Another‚” researchers Alexandre Yersin and Shibasaburo Kitasato independently used the microscope to identify the cause of the bubonic plague. Compound microscopes—microscopes that use more than one lens—were invented around 1595. These first microscopes

9.07 close up! "If you want a close-up view you should move yourself if it is possible. The trouble is that so many photographers seem afraid to move in." (Lord Snowdon) How can moving close to a subject change and improve a photograph? Why do you think many photographers use their lens to get closer rather than moving closer to the subject? Moving close to a subject can help change and improve a photograph because your getting in closer to the subject and you will be able to see different things

Susan Sontag’s claim it is clear that photography limits people’s interpretation of the world. This claim I false because pictures rang from people in complete destitution as seen by photos of Jacob Riis to people having a good time on vacation. Because of this diverse collection of pictures‚ people see the world as it is instead of "more than it really is". This is seen through actions of Hitler various world events such the Vietnam War and the Kent State incident as well as literature like The

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

The electron microscope‚ instrument that produced the first magnified image showing three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic
