A Spectrophotometer
it's called an ALS alternate light source. it can project light in different wave lengths and spectrums.
There are 3 spectrums of light measured in nm nanometers. There are 2 downstream spectrums and 1 upstream spectrum. 1490 carries voice and data downstrem. 1550 carries video downstream. 1310 carries all upstream. Generally there are acceptable levels at an ONT. This stands for Optical Network Terminal. Fios has its own standards. 1490 should be no lower than -28nm and 1550 should be no lower than -6. You can do more research if you want to get more detailed specs.

The list - for this Answer - is quite lengthy: in fact everything that we know about Stars and all other celestial entities comes from the spectrums of the observed Light.
Yes and no. Yes in their true nature (ie: detection by machines) and no in our reality (ie:detection by our senses) It depends on how infinite the discerning (cutting up) of each type of frequency is. On the other hand, light and sound do have limited spectrums but those spectrums have inifinite frequency possibilities in between
Yes it does. Use the 'light sensor mode'. You can not use the default 'view' program to test the sensor.
The field of view in an optical device is typically illuminated by a light source within the device, such as an LED or a light bulb. The light is directed towards the object being viewed and helps enhance visibility and clarity within the field of view. Additionally, some devices may use mirrors or lenses to control and distribute the light evenly across the field of view.
Spectrums
Use a pinhole or a dark-filtered optical device to project the sun's image on a light surface,and view the image.
False, electron microscopes use electrons to view specimens which have been treated with special metallic "dyes". (the clue is in the name)
Spectroscopy is basically the study of the spectrums of visible and non-visible light rays. Specifically, it is determining the output of radiation an object has along the spectrum. This is called a wavelength.
Because a leaf normally has green pigment in it called chlorophyll. These pigments absorb all the spectrums of the light except for the green spectrum, which is why leafs appear green.
