TL; DR Short answer is the energy from the photon causes the electron to jump. Conservation of energy dictates that the photon would lose some energy, and it would be from the particle matter that it would act this way. Long Answer This is called the photoelectric effect. Basically this is caused by an energy transfer from a photon, acting as a particle ...
EM waves are formed when an electric field couples with a magnetic field. The magnetic & electric fields of an EM wave are perpendicular to each other & to the direction of the wave. The wavelength is just that--the length of the wave through one frequency cycle.
In principle, yes. Sound waves are compressions in a medium, which in principle can be seen if the density contrast between wave crests and troughs is large enough, and the wave speed is small enough. In "everyday object", such as the air, neither of these conditions are fulfilled. But one example of visible sound waves are the so-called baryonic acoustic ...
Blind people see in their brain 3 dimensional images with echo location. When they hear sound it can be interpreted as color or shapes. Also if you put a vibration to your closed eyes you'll see all kinds of patterns of color simulator to pressing on them.
Yes. High intensity low frequency sound makes your eyeballs vibrate in your head, so you really can see (and feel) it. On a related topic, you can find the damped resonant frequency of your eyeballs by looking at the sweep line on an oscilloscope whose timebase has been set to around 50mS. If you then hit yourself downwards on the top of your head you will ...
What we perceive as "sound" are (mechanical) oscillations of molecules from the source to the ear. This is for example why you cannot hear anything in vacuum, because there is no matter to oscillate. Light on the other hand is an electromagnetic wave. Therefore, there cannot be sound in our visual spectrum. It's in the wrong category. However, if you want ...
No, there is not. The eyes are receptors of electromagnetic waves and therefore they don't percipe sound. However, there are cases when you actually can see a sound effect on your own eyeballs, but they are unusual and a bit crazy. E.g. if you play low frequencies on a trombone and watch a screen with some repetition rate, then you can sometimes see an ...
According to microwave schematic it is 50 Hz 2000 Watt radiation. And metal shield don't protect good enough. It is danger to be near microwave.
I'll guess that the most significant thing about the wavelength of light to the average person is simply the colors we visualize. Interestingly, the typical three types of cones in the human retina lose all information about frequency once the "photon" is detected. Thus, for a stream of photons all of one particular frequency, we detect three analog signals ...
