- Q: How do you measure light year? I know light year (ly) is an unit of time taken by light to travel in one year. I am looking for details like concept or experiment used to measure the light year. Being at a point on earth, how do you say this light has travelled one light year and the light has travelled 3 or so light years?
- I know light year (ly) is an unit of time taken by light to travel in one year. Wrong. A light year is a unit of distance, representing the distance light travels in one terrestrial year. IT is equal to a little under ten trillion kilometers, which is to say about 70000 times the distance from the Earth to the Sun.
- Q: I want to put a light in my loft that can be switched on and off using the switch for the light on my stairs how do I do this??
- It's not too difficult if you can run an electrical cable from the existing light to where you want the new light.
- Q: How many of you are are light-sensitive? And what do you do to help in places where the light hurts your eyes?
- I've always had my eyeglasses tinted. I don't know if this is true or not but Dr.s say people with light eyes are more light sensitive than others. Good Luck
- Q: Gravity bends light, i know that thats true, but how? if light cannot be slowed in a vacuum, how can it be bent without being slowed?
- Not quite - general relativity tells us that gravity bends space. Light travels straight through space; if the space is bent, it makes the light look bent, even though it isn't.
- Q: What is lighting design?
- Lighting design is installing various types of lighting to create the type of effect that you want. It deals with the the installation of track lighting, recessed lighting, fluorescent lighting, chandeliers and cable lighting. It Also requires working with basic electrical wiring, installing dimmers, three-way switches and other specialty lighting features.
- Q: What is the chemical relationship between the light dependent and the light independent (carbon fixation) reactions of photosynthesis? In what part of the chloroplast does each occur?
- The light independent reaction occurs in the stroma of the chloroplast, and the light dependent reaction occurs in the thylakoid of the chloroplast. In the light dependent reaction (the two photosystems), products from there are transported to the light independent reaction. In the light dependent reaction, light (from the sun)splits two water molecules, and the H+ remains on the side, ready to be moved on to Photosystem I from II via the electron transport chain. Oxygen is released during Photosystem II. ATP synthase binds ADP and P together as the hydrogen atoms travel with the ATP synthase. In Photosystem I, NADP+ accepts and carries two pairs of hydrogen atoms, and while doing so, becomes NADPH. ATP and NADPH goes to the Calvin Cycle (light independent). In the Calvin Cycle, NADPH and ATP is taken in, and NADP+ and ADP is released to the light dependent reactions. Carbon dioxide is taken in, and glucose is released in the light independent reaction.
- Q: Would this product give light brown hair blonde highlights?
- no it will just damage your hair use bleach to do blonde the sun in will burn your hair so bad DONT USE IT
- Q: examples of how light enery travels
- Light travels in electromagnetic waves through most spaces however in a vacuum it travels in a straight line. Light travels at approximately 299,792,258 meters per second. Some of light travel can be seen, some of it is invisible.
- Q: Some people say light produces heat, but could the heat be the one producing the light? Think about it, many stars are extremely hot and produce a lot of light. a torch produces light also. Electricity shoots into a tungsten on a lightbulb making it very hot, and produces light. Any answers?
- Light is not a byproduct of heat. Heat occurs in different forms. One form, heat radiation, is of the same nature as light, i.e. electro-magnetic waves, just of different wave lenghts.
- Q: how fast dose light move. mph or light years brake down
- speed of light is 186,000 miles per second or 669600000 miles per hour 1 light year is the distance light travels in 1 year. 669600000mph X 24 hr per day X 365 days per year = 5865696000000 miles per year = 1 light year.
