When he did this, he was able to detect electrons being emitted from the surface. This was Einstein's explanation: If the energy in light comes in bundles, then one can think of light as containing tiny lumps, or photons. When these photons strike a metal surface, they act like billiard...
Infrared photography can detect temperature differences. Snakes can actually detect infrared radiation, which is how they are able to locate warm-blooded prey in total darkness. Visible: This is the only part of the electromagnetic spectrum we can see. We see the different wavelengths in this ...

Amateur radio is limited by the distance that radio waves can travel. To send a signal to the other side of the world requires calculated timing and more than a little bit of luck. Every 11 years, for example, there's a peak in the number of sunspots produced by the sun, which increa...
I don't think you can assume that, because a Born rigid congruence in the presence of a gravitational wave cannot possibly be a geodesic congruence; if it were, then LIGO would give a null result and would not be able to detect GWs.Nov...
To solve this problem, extra data bits are added that allow the drive to detect single-bit errors and correct them. Because a scratch or a speck on the CD might cause a whole packet of bytes to be misread (known as a burst error), the drive needs to be able to recover from such ...
from its source to your ear. The same thing happens when you hear sounds underwater or through walls (liquids and solid propagate the sound waves as well). However, in the vacuum of space, there are no molecules to propagate sound waves and you don't hear anything. The movie poster of...
Light fields are also affected by gravitational waves! Presenting strong evidence that LIGO did not detect gravitational waves in the GW150914 event According to General Relativity, a passing gravitational wave can "shrink" objects and change their lengths. On this basis, the Laser Interferometer Grav...
Another part of the MRI system is a set of coils that transmit radiofrequency waves into the patient's body. There are different coils for different parts of the body: knees, shoulders, wrists, heads, necks and so on. These coils usually conform to the contour of the body part being ima...
