Question

can light absorption be dangerous from
us? Explain by giving scientific evidences​

Answer 1

Answer:

Light absorption is a process by which light is absorbed and converted into energy. An example of this process is photosynthesis in plants. However, light absorption doesn’t occur exclusively in plants, but in all creatures/inorganic substances. Absorption depends on the electromagnetic frequency of the light and object’s nature of atoms. The absorption of light is therefore directly proportional to the frequency. If they are complementary, light is absorbed. If they are not complementary, then the light passes through the object or gets reflected. These processes usually occur at the same time because the light is usually transmitted at various frequencies. (For instance, sunlight also comprises lights of various frequencies; from around 400 to 800 nm). Therefore, most objects selectively absorb, transmit, or reflect the light. When light is absorbed heat is generated. So the selective absorption of light by a particular material occurs because the frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate.
