A ground breaking new tool used to study the heavens was introduced in the 17th century. This tool was known as the telescope. It revealed the cosmos in a different way than our naked eye could ever perceive. The telescope opened doors to countless stars‚ nebulae‚ galaxies‚ and a slew of never before seen wonders. With its creation came limitations and caused the need to improve and upgrade the methods in which the telescope functioned and find new ways of viewing the heavens.There are three main

Brief History of Canon Cameras | | | | | | 1933. Goro Yoshida and his brother-in-law‚ Sabura Uchida‚ founded the Precision Optical Instruments Laboratory. The goal: to make cameras to compete with the most advanced German models of the day. 1934. Japan’s first domestically-made 35mm focal-plane shutter camera‚ the "Kwanon’ -- named after the Buddhist Goddess of Mercy. 1935. "Canon" trademark registered. 1935. Hansa Canon cameras offered for sale at half the price of a Leica.

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

equiconvex lens (made from a glass of known refractive index) and an adjustable object needle APPARATUS: A convex lens‚ an optical needle‚ a plane mirror‚ a clamp stand‚ a spherometer‚ a plumb line‚ metre scale‚ water and turpentine oil Theroy : Let’s add small amount of water on a flat‚ plane surface and place a convex lens over it. This forms a plano-concave lens of water between the lower surface of convex lens and plane mirror. Let f 1 and f 2 are the focal lengths of water lens and convex lens respectively

Refraction in Biconcave Lens Now let’s investigate the refraction of light by double concave lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are travelling parallel to the principal axis. Upon reaching the front face of the lens‚ each ray of light will refract towards the normal to the surface. At this boundary‚ the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in

the Thin-Lens Equation: Where f is the focal length of the lens‚ do is the object distance and di is the image distance. From the Thin-Lens Equation we are able to mathematically see and understand many interesting and valuable situations that arise when working with lenses. When the object is the same distance from the lens as the image‚ for instance‚ we can easily verify that the focal length must equal half the image (object) distance or if the object is very far away from the lens (at infinity)
