The direction of light can be changed in 2 ways. One way is refraction which is usually done by a lens (eyeglasses do this). The other is reflection, most often done by a mirror. Telescopes are almost always based on reflection and/or refraction designs. A reflective telescope has at least one curved mirror, often 2 curved mirrors which focus light by reflecting a larger area of natural light on a smaller spot.

How can I photograph shiny stainless steel objects, without getting a reflection on the surface?


You will need a light source that does not reflect. Typically, you can move the lights so the reflections don't show, or use a very large lit surface so the reflection is softened.

Since polished subjects do reflect, you may find that you need some reflections just to show that the object is shiny.... Without that, it won't look right.

My sir told that transparent glass do not reflect any ray. We see things by reflect only.e.g moon. Reflect means not only like face mirror. Then how we can see mirror.


There is no mirror in the scanner. It is supposed to be clear glass. The light comes on to scan the item in the scanner.
Don't understand your problem. If the light does not come on the printer isn't plugged in or turned on when scanning.

What is the soft key


Look at the display on your phone. You'll see some labels at the bottom. These correspond to the keys just below the display. The meaning and function of these keys vary according to context, and the labels change to reflect that. Thus the keys are "soft" in that their meanings change.

What does Multi-Gesture mean?


Multi-touch or multi-gesture, has been implemented in several different ways, depending on the size and type of interface. Both touchtables and touch walls project an image through acrylic or glass, and then back-light the image with LEDs. When a finger or an object touches the surface, causing the light to scatter, the reflection is caught with sensors or cameras that send the data to software which dictates response to the touch, depending on the type of reflection measured. Touch surfaces can also be made pressure-sensitive by the addition of a pressure-sensitive coating that flexes differently depending on how firmly it is pressed, altering the reflection.[2] Handheld technologies use a panel that carries an electrical charge. When a finger touches the screen, the touch disrupts the panel's electrical field. The disruption is registered and sent to the software, which then initiates a response to the gesture.[3]

Microwave shuts off and reflects f-9.


F 9 means Fault Code 9. This means that the Microwave has developed a "Fault" and the "Brain" has determined what it "Thinks" the problem is and outputs that "Code" so a serviceman can consult the manual, to find the exact "Fault". In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Mirrors going bad. White and black spots are apperaing on my screen. More each day. It is my understanding that tiny mirrors are not turning off or on. Purchased DLP 46'' Samsung January 2007


Well here's the scoop. White spots mean that the mirrors are stuck "on" reflecting light. Black spots mean that other mirrors are not actuating and are not reflecting light. In any case the DMD bs or the DMD chip needs to be replaced by a trained Samsung tech only.
The DMD bd controls the DMD chip.

Blue CRT issues?


Yes the puddle is related to the Blue CRT coolant leaking. You are most likely going to need a new Blue CRT drive circuit board and quite possibly a new Blue CRT if the CRT got too hot from not haveing a sufficent supply of coolant. You can get replacement CRT drives and CRts at the following link.

What is difference between reflection and refraction?


Here is refraction

Refraction is the bending of light as it passes from one substance to another


Here is reflection

Reflection occurs when light changes direction as a result of "bouncing off" a surface,

i think the definitive difference is a refraction is a bend in the light where a reflection is a redirection of it

I purchased "tasty planet" from reflective entertainment inc but have not received my activation code. i have reaplied for it but still dont have it. keep being told item no:eabzrprdk46cvr3xej937...


That's great, but why are you asking anyone else than Paypal or Reflective Entertainment what the problem is?  If you want codez this isn't the site.  Patently, PayPal takes a long time to settle for merchants; doublecheck your browser history of the purchase to cc with PayPal as an issue if you still have no code (check y'r spam folder, etc.) and give Reflective a carbon copy, expecting them to make good.  I mean, especially send Reflective a copy of the PayPal screen with personal details redacted (smudged out.) And this ain't a PC Desktop problem, but I'd put it down under Software/Tasty Planet....

How is a flashlight both luminous and nonluminous at the same time?


At first light it DOES sound a bit confusing.
First, the definition of the term 'NON-LUMINOUS'; 'Not capable of PRODUCING light but can be capable of REFLECTING light from another source'.
For instance, our MOON is NON-LUMINOUS as it REFLECTS light from the Sun. The SUN is LUMINOUS as it produces light that is REFLECTED off the surface of the moon. And so, LUMINOUS means capable of PRODUCING light.
Now closely examine your flashlight.
The BATTERIES produce electrical energy which is transferred to the BULB which emits light, thus LUMINOUS. The tiny little BULB emits quite a lot of light for its small size. However, the bulb is contained within a concave silvered cone which REFLECTS,(NON-LUMINOUS) gathers and channels the emitted light from the BULB (LUMINOUS) into a BEAM which ILLUMINATES whatever you are pointing the flashlight at.
Our cameras would be just paperweights if there were no NON-LUMINOUS surfaces for the light to REFLECT off of, back into the camera lens, onto the 'plate' thus etching the image. For example, take a photograph in the dark without the flash and what do you get. No LUMINOUS, no NON-LUMINOUS.
And so there we have LUMINOUS and NON-LUMINOUS, ILLUMINATING our lives. Enjoy! :)
