No - light is not formed by molecules.
Molecules are groups of atoms bonded together by chemical bonds. Examples are water (two atoms of hydrogen and one atom of oxygen, H2O, and methanoic
acid, HCOOH).
Light is formed by elementary particles of the boson category called photons. Since in quantum mechanic particles are described by a quantum field, light can also be seen as an electromagnetic field that can be described through two related vector field: the electrical and the magnetic field (or through a Minkosky
four dimensional tensor collecting the two vector components). To be precise visible light (that we generally call simply light) is an electromagnetic field oscillating in a well precise frequency interval where the human eye is sensible and can detect photons. Since different frequencies of visible light are sensed like different elementary colors by the human brain elaborating information coming from eyes, in the visible frequency band light frequencies are also called
colors.
Photons are responsible of electromagnetic interactions, so that many chemical bonds forming molecules can be interpreted in quantum mechanics as exchange of photons between the involved atoms. For example this is the case of the ion bond binding the Cl (Chloride) and Na (Sodium)
ions in common table salt
The light energy absorbing molecules, such as chlorophyll, are found in the chloroplasts of plant cells. These molecules are responsible for capturing light energy and initiating the process of photosynthesis.
chlorophyll
The energy from light is stored in the form of chemical energy in the molecules ATP and NADPH, which are produced during the light reactions of photosynthesis. These molecules then power the calvin cycle to produce sugars.
Photons of light strike chlorophyll molecules and excite electrons.
There are no glucose molecules produced in the light reaction. The light reaction produces ATP and NADPH, which are used in the Calvin cycle to produce glucose from CO2.
The wavelength of visible light is larger than molecules.

No.
chlorophyll
The oxygen molecules are released
molecules or particles that can absorb photons of light. These molecules have electrons that can be excited by the incoming photons, leading to the absorption of light. Without such molecules or particles, light would simply pass through without being absorbed.
Colored molecules that absorb light are usually organic compounds that contain conjugated double bonds or transition metal ions in their structure. These molecules absorb specific wavelengths of light, causing them to appear colored. The absorption of light by these molecules leads to the excitation of electrons to higher energy levels.
When the frequency of light matches the natural frequency of molecules in a material, light is absorbed by the material. This phenomenon is known as resonance absorption.
All molecules will absorb light to a greater or lesser degree
No. Atoms and molecules are far smaller than the wavelengths of visible light, so light cannot be used to image them.
Light waves are absorbed through air when the molecules in the air absorb the energy carried by the light waves. This absorption occurs due to interactions between the light waves and the electrons in the air molecules, causing the molecules to vibrate and convert the light energy into other forms of energy like heat. The amount of absorption depends on factors like the wavelength of the light and the properties of the molecules in the air.
