Why do shorter wavelengths get absorbed into gas molecules rather than long wavelengths?
Answer:
atoms comprise of tightly bound nucleus of protons and neutrons (protons have positive charge and neutrons are neutral). Electrons exists in pre-defined orbits around the nucleus and are negative particles. predefined means that they can only exist at certain distances. Because these distances are associated with a kind of energy, it means these electrons only exist at predefined energy levels. Now, if you give an electron not enough energy to reach the next energy level (by sending a photon near it), it cannot exist in-between therefore it will not absorb that energy, therefore it will be transmitted (or will pass through the atom), but if that light particle does have the right energy, then the electron will absorb it and it will jump up an energy level, hence that energy is absorbed and we say the gas is opaque to that frequency. After the absorption, the electron may jump down again and emit a photon, the frequency of which is dependant on the temperature of the substance in question (ever wonder why metal gets red hot??).
the energy of a light photon is E=hf, where f= frequency and h is a constant, and of course E=energy.
wavelength is inversely proportional to frequency, which means longer wavelength is less energy than shorter wavelength light.
This means that a photon of energy E has a frequency of E/h, therefore you can see that the energy of a light photon is directly related to its frequency, and putting that together with what we know about electron only absorbing light photon energy of certain energy values, we can see why only certain wavelength of light gets absorbed.
There are other things that can happen to photon that don't involve bound electrons too.

Is green reflected?
Green is not reflected, but rather it is absorbed by objects. When we perceive an object as green, it means that the object is reflecting green light wavelengths and absorbing all others.
Why does gold not reflect the color blue?
Gold absorbs and reflects certain wavelengths of light, resulting in its characteristic yellow color. Blue light has a shorter wavelength than yellow light, causing it to be absorbed rather than reflected by gold. This is why gold appears yellow and does not reflect the color blue.
Why are sky's blue why not violet?
The white light of the Sun consists of many wavelengths. When seen separately, each wavelength corresponds with a different color. The air molecules and particles of matter that make up our atmosphere scatter some of the Sun's light as it travels to Earth, especially the shorter wavelengths that give us the color blue. Coming to us from all angles in the sky, these light waves make the sky appear blue.
How does changing wavelength in the activity vary the light that you see?
Changing the wavelength of light can alter its color perception. Shorter wavelengths (like blue and violet) are perceived as cooler colors, while longer wavelengths (like red and orange) are perceived as warmer colors. This is due to the way our eyes interpret and process different light frequencies.
When a light from a gas passed through a prism why is there only a certain number of lines rather then a continuous spectrum?
When light from a gas passes through a prism, the lines seen are caused by the specific wavelengths of light emitted or absorbed by the gas atoms. These lines correspond to the energy levels of the atoms, leading to discrete spectral lines rather than a continuous spectrum. Each line represents a transition between energy levels, resulting in distinct wavelengths being observed.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
Is green reflected?
Green is not reflected, but rather it is absorbed by objects. When we perceive an object as green, it means that the object is reflecting green light wavelengths and absorbing all others.
Why does gold not reflect the color blue?
Gold absorbs and reflects certain wavelengths of light, resulting in its characteristic yellow color. Blue light has a shorter wavelength than yellow light, causing it to be absorbed rather than reflected by gold. This is why gold appears yellow and does not reflect the color blue.
Does molecules have cell?
No, molecules do not have cell, rather a cell have molecules in it.
What absorbs wavelengths of light different from those absorbed by chlorophyll?
Other pigments, such as carotenoids and phycobilins, can absorb wavelengths of light different from those absorbed by chlorophyll. These pigments are found in various photosynthetic organisms and help to broaden the range of light that can be utilized for photosynthesis.
What colors are absorbed by black shirt?
white and something else

What color wavelengths of light do plants primarily absorb?
Different plants absorb different colors. Even different parts of plants absorb different colors. The color you see the plant as is the color being reflected rather than absorbed by the plant.
Is color a physical or chemical reaction?
Color is a physical property of an object that arises from the reflection of light off its surface. It is not a chemical reaction, but rather how our eyes perceive different wavelengths of light interacting with the molecules in the object.
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
