What is the difference between fluorescence and phosphorescence?
Fluorescence and phosphorescence are both processes where a substance absorbs and then emits light. The key difference is in the timing of the light emission. Fluorescence happens almost immediately after the substance absorbs light, while phosphorescence involves a delay in the emission of light, which can last from milliseconds to hours.
When a substance transmits no light?
When a substance transmits no light, it means that the substance absorbs all the light that comes in contact with it, preventing it from passing through. This could be due to the substance's molecular structure or composition, which causes it to absorb all wavelengths of light rather than allowing them to pass through.
What is an absorbtion spectrum?
An absorption spectrum is a graphical representation of how a substance absorbs light at different wavelengths. It shows the pattern of absorption as peaks and valleys, indicating the specific wavelengths of light that are absorbed by the substance. This can reveal information about the substance's composition and structure.
What is the ability of a substance to reflect light?
The ability of a substance to reflect light is known as reflectance. It is determined by the material's surface properties such as smoothness, color, and angle of incident light. A substance with high reflectance will appear bright and shiny, while a substance with low reflectance will appear dull.
What substance to appear white what must happen to all wavelengths of light?
must be reflected

What substance that absorbs light?
Chlorophyll pigments absorb light during photosynthesis.
What are the infrared wavenumbers of the substance in question?
The infrared wavenumbers of the substance are the specific frequencies at which it absorbs infrared light.
What happens to the light when it hits?
it absorbs the radiation from it making it harmless
What best defines the physical property of color?
A measure of how a substance absorbs and reflects light
When chlorophyll absorbs light energy what happens to its electrons?
It becomes excited.
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
What is the name of the substance in plant cells that absorbs light?
chlorophyll =] check the spelling though
