Photon Led
Phantastic Photon lab questions?
i’m doing a lab called Phantastic Photon, and i’m stuck on the last 2 questions. any help would be appreciated.
9. Photoresist, a chemical used in making computer chips, changes its solubility when exposed to ultraviolet light. Why are cleanrooms where photoresist is used illuminated with yellow light?
10. A silicon photodiode used as a light dectector can only absorb photons of energy greater than 1.1 eV. Will it absorb photons from the infrared LED?
9. They make them with yellow light because it is less harmful to the chemical makeup, photoresist soaks up UV rays like a sponge.
10. Absolutely, i did a lab on this back in digital electronics where we too a photodiode and an LED and connected them with a piece of heat shrink.

LED GU10 Bulb and Their Use in Society
LED bulbs, or light-emitting diode bulbs are a semiconductor light source which is used within a wide range of devices as a source of lighting. During its introduction as a practical electronic component in 1962, LED GU10 Bulb were produced to emit low-intensity red light. However, through thorough designs and different advances within the field, more modern versions surfaced across the visible, ultraviolet and infrared wavelengths which provided a very high level of brightness. As the designs have evolved further, LEDs are now able to produce light which provides a variation of wavelengths from visible to ultra violet and infra red light. In fact, the overall design and manufacturing of LEDs has grown to such a scale that they are now commonly used in a wide range of electronic devices such as televisions as a means to improve the quality level of picture watching.
LEDs are diodes which mean that electricity can only travel through them one way. When a diode is switched on, electrons are able to recombine with holes within the device which releases energy in the form of photons- this process is called electroluminescence. It is this small gap where the LED MR16 Bulb is produced and when one surface is positively charged, the opposite will be negatively charged, electricity will flow and where the two charges meet, energy will be released in the form of light. The colour of the light which is emitted is dependent on the energy of the photon and the size of the energy gap within the semiconductor. It is due to their small scale that LEDs have been used in a wide range of devices which surround us every single day. This is not only due to its small scale, but also as they are low in cost but still produce a high strength of light for the user- in many cases, this quality of light surpasses the light which can be produced by other, similar light sources. In these instances, the Led is encased within a design which allows for the light to be channelled and reflected to the best of its ability without wasting any of the light which is emitted.
One of the most noticeable uses of LED MR16 Bulb is within traffic safety lights. This is in both the red/amber/green lights and highway lights which notify you of an accident/construction site, etc. These lights work in a flashing mode, which make them more noticeable and much more effective in terms of their use. They are also used around the home-often as an alternative light source to fluorescent lighting. This can be used for tasks such as under cabinet lighting, reading lamps, security lights and outdoor lighting. However, the use of LEDs also span over to many of your electrical goods too. Mobile phones, Televisions and Computer screens all use LEDs in some form in order to provide you with a set amount of lighting which when you think about it, shows just how far this tiny piece of lighting has come from 1962.

Vladimir Poponin DNA Phantom Effect – (Is this BS? Its not on Snopes)?
After researching about Holograms, which led me to DNA, which led me to DNA experiments, I ran into an article I had to snope in regards to an alleged experiment that took place by a Russian Scientist i.e. Vladimir Poponin which goes as follows:
The first reported experiment was done by Dr. Vladimir Poponin, a quantum biologist Dr. Vladimir Poponin, with a Ph.D. in physics and another in mathematics from the Russian Academy of Science.
First a container was emptied, therefore creating a vacuum within it. Then, the only thing left were photons (particles of light); he measured the distribution or location of those photons and found they were completely random inside the container. This, of course, was the expected result.
But surprisingly enough, then some DNA was placed inside the container, and the distribution (location) of the photons was remeasured again, but this time the photons were lined up in an ordered fashion, aligned with the DNA.
Is this BS?
Yes, it’s BS.
Not least because while “quantum biology” is an emerging field of study, it has nothing to do with the kind of things Poponin is supposedly researching.
Quantum biology applies quantum theory to the study of the behavior of biochemical processes.
“Quantum Biology” as practiced by guys like Vladimir Poponin and Glen Rein is pseudoscientific, New-Agey BS.
