Infrared Frequency Puns

A list of puns related to "Infrared Frequency"

Infrared laser laboratory equipment? Made in France by Groupe Delta, weighs about 10 kg. It has two probes/emitters and then there is this weird metal rod which detects contact with one of the probes. Possible to adjust the frequency of the probes and it seems to measure Watt and energy in Joule. reddit.com/gallery/rjvvna

do vein detection devices use infrared lights? and if they do, how do they show infrared light to the naked eyes? I think the reason is that they aren't really using infrared light but a visible light that is close to the infrared frequency. is that it?

Were the infrared waves imaged in the CMB once higher-frequency waves?

I'm a little fuzzy on the electromagnetic spectrum. Do all EM waves start out at Gamma rays and then get weaker (lower frequency) over time? Or is it possible for naturally occurring phenomena, like the universe at the time of the Big Bang, to emit waves at a lower frequencies. Obviously man-made equipment can do so...

Infrared Light Frequency

Is there any way to determine the frequency (if it is even called frequency) of an infrared remote. I have heard of different nm remotes and receivers but how do i know which frequency/wavelength of a remote?

In the way an optical prism refracts light to show the visible spectrum, are there materials that act as prisms to other frequencies of the greater EM spectrum - eg, something that refracts ionizing radiation to produce a spectrum between Extreme UV and Gamma rays or maybe Far infrared and UHF?

Reading Infrared Frequency and Modulation

Hello r/arduino,

I have an infrared device that I want to replicate. I've tried finding documentation online describing the data needed, but there is none. Without knowing anything about the device-- how can I reproduce the exact infrared beam myself on my own infrared bulb? Is there some type of sensor I can buy that I can connect to my arduino or raspberry pi to record this data for me?

Any help is appreciated.

Thanks!

Why are the light sources in frequency domain near-infrared spectroscopy so low in frequency (100 MHz)?

I read on Wikipedia and some other sources that: "NIR laser sources provide an amplitude modulated sinusoid at frequencies near one hundred megahertz (100 MHz)".

I also read that NIRS light is typically in the range of 700 - 2500 nm, which corresponds to a much, much higher frequency than the previously mentioned 100 MHz. This doesn't make much sense to me. Am I not understanding the initial statement, or is my conversion wrong? Maybe it would help if I knew what exactly is meant by "amplitude modulated sinusoid".

Thank you.

Concerning the photoelectric effect, if an electron's energy is nearly proportional to the frequency of the incident photons, why don't solar panels work on cloudy days? Doesn't UV light, which is higher energy than visible and infrared, pass through clouds?

Or don't current solar panels currently work with UV light? And is there any progress towards engineering solar panels that can work efficiently in the UV range?

Scientists use terahertz spectroscopy to study a single molecule. Terahertz light lies between infrared and microwaves on the electromagnetic spectrum. Its frequency can excite molecules, causing them to vibrate, but its long wavelength makes it near-impossible to be focused onto single molecules. iis.u-tokyo.ac.jp/en/news…

Infrared Remote Carrier Frequency

This may be a silly question but here goes.

I'm trying to make a kind of TV-B-Gone device out of the raspberry pi. This device pulses an infrared LED on and off at different intervals which corresponds to an off single sent by a TV remote control.

I have the timings but I'm confused at what is meant by the Carrier Frequency of the LED. I know that this needs to be at 36.09 KHz but not sure how it is controlled. do different LED's output at different carrier frequencies or are they all the same and the carrier frequency is changed in software somehow?

Thanks in advance for any help.
