What kind of electromagnetic radiation could be used to see molecules?
inferred rays
What is a visible ray?
"Visible" electromagnetic radiation is radiation with wavelengths between roughly 390 to 750 nanometers. (0.000350 to 0.000750 millimeters) -- If electromagnetic radiation with a wavelength in this range enters your eye, you know it, because the retina of your eye responds to these wavelengths. -- If radiation enters your eye but its wavelength is not in this range, you don't notice it. -- If there is radiation in the neighborhood with wavelength in this range but it doesn't enter your eye, then you don't notice it. (If a flashlight shines a spot on the wall across the room, you don't see the shaft of light on its way across the room. You see it only after the light hits the wall and some of it bounces off the wall and into your eyes. )
Why we cannot see molecules of water?
It's about wavelength and size. The wavelength you use to look at an object has to be shorter than the object. And visible light has a wavelength that is longer than a molecule.
What is meant by ionising radiation?
See the Wikipedia article 'Ionising Radiation' of which this is the introduction. Ionizing radiation consists of subatomic particles or waves that are energetic enough to detach (ionize) electrons from atoms or molecules. Ionizing ability depends on the energy of the impinging individual particles or waves, and not on their number. A large flood of particles or waves will not cause ionization if these particles or waves do not carry enough energy to be ionizing. Examples of ionizing particles are energetic alpha particles, beta particles, and neutrons. The ability of electromagnetic waves (photons) to ionize an atom or molecule depends on their wavelength. Radiation on the short wavelength end of the electromagnetic spectrum - ultraviolet, x-rays, and gamma rays - is ionizing.
How does the wavelength of the infared portion of the electromagnetic spectrum differ from that of the visible portion of the spectrum?
I have no clue Laugh out loud
What kind of electromagnetic radiation could be used to see molecules?
inferred rays
What is the wavelenght of UV?
The wavelength of UV radiation energy is typically shorter than the wavelength of normal sunlight radiation, so you can't see UV
What are facts about x rays?
X-rays are a form of electromagnetic radiation with a very short wavelength. They are used by doctors to see inside the human body.
Why cant you use visible light to see molecules?
because light used to see an object must have a wavelength
What is light classified as?
Light is an electromagnetic radiation. Our eyes are sensitive, the E/M radiation at the light wavelength. Hence we see light. The E/M radiation adjacent to light are Infra-red(IR) and Ultra-violet(UV), which we do not see.

What kind of energy from the sun helps people see?
Electromagnetic radiation between 490-790 terahertz, or about 390-700 nanometers wavelength.
Can refracting telescope allows scientist to see carbon molecules?
Atoms can't be seen because they are smaller than a wavelength of light
What wavelength of light must be used to see Eagle Nebula?
Infrared

Is infrared radiation the same as radiation?
No, if you look at a chart of the electromagnetic spectrum, you will see that microwave radiation is a longer wavelength ( approx. 1x10^8 Hz to 1x10^11Hz). Infrared is a smaller wavelength - approx 1x10^13 to ^15. The smaller the wavelength, the more able it is to penetrate matter. Radio waves do not penetrate our body because they are so very large, on the flip side, x-rays are very very small wavelengths and therefore can pass through our body.
What processes produce the difference colors we see in opaque objects?
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.
