What is a Gender Lens? Think of a gender lens as putting on spectacles. Out of one lens of the spectacles‚ you see the participation‚ needs and realities of women. Out of the other lens‚ you see the participation‚ needs and realities of men. Your sight or vision is the combination of what each eye sees. Gender is about relationships between men and women. Gender equality is about equal valuing of women and men - of their similarities and their differences. We need equal‚ respectful partnerships

REFRACTION THROUGH A LENS Lens: Lens is a transparent refracting medium bounded by two curved surface which are generally spherical. Types of lens: Generally there are two types of lens: 1. Convex lens: It is a lens which is thicker at the middle and thinner at the edges. It is also called converging lens as the light rays converges on passing through it at a point. Focal length of convex lens is taken as positive. 2. Concave lens: it is a lens which is thicker at the edges and thinner at the middle

the image formed by a converging lens plus diverging lens. Background This experiment focused on a simple lens system. A simple lens is a piece of glassware that is spherical on one side and flat on another side‚ or spherical on both sides. There are two different types of lenses. A converging lens‚ also called a positive lens‚ and a diverging lens‚ also known as a negative lens. A converging lens thicker middle area than top and bottom‚ and the diverging lens has a skinnier mid-section. When

The Fresnel Lens Do you know what the largest light house in America? Or how many steps it takes to get to the top? I do. It’s Cape Hatteras light house in Buxton‚ NC. It was completed in 1971 and stands 193 feet in the air. It takes 268 steps to climb to the top. I visited this light house in August of 2010 I had the pleasure of seeing the 6‚000 lb. bronze and crystal lens. In 1803 it was replaced due to being damaged by vandals. Light houses from the 18th century used burning candles‚ oil lamps

every aspect of life. In the poem‚ “If I Could Tell You‚” Auden works through the idea of time being superior and how it brings an overall uncertainty— especially to love‚ and creates a desperation of knowing. By looking through a Historical Biographical Lens‚ it would make sense to identify the speaker of the poem as Auden himself. He seems to be writing an answer to a question that someone‚ at one point in time‚ has asked him. However‚ Auden is unable to answer the question‚ stating‚ “if I could

Name Instructor Course Date of Submission Fresnel Lens Discovery The Fresnel lens was discovered in 1819 by a French physicist named Augustin-Jean Fresnel. He served as a commissioner of light houses under the French Government (Levitt and Theresa 1). First‚ Fresnel developed a lighting system that consisted of reflector panels placed behind oil-lamps. However‚ this proved to be inefficient since it converted just about 3% of the total light emitted into useful light‚ which was insignificant (Levitt

Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging lenses and negative for diverging lenses

REGULAR TISSUES CAN SCRATCH THE LENSES. __F__ 2) The coarse adjustment knob maybe used in focusing with all objective lenses. COARSE ADJUSTMENT IS ONLY USED ON SCANNING POWER. __T__ 3) When beginning to focus‚ the lowest power lens should be used. __T__ 4) Resolution decreases as the amount of light coming in on
