What two wavelengths of light are most absorbed by the above pigment?
The pigment primarily absorbs green and red wavelengths of light, reflecting back other colors which results in its observed color.
What determine the color of a translucent material?
The color of a translucent material is determined by the wavelengths of light it absorbs and reflects. The material's molecular structure and composition play a key role in determining which wavelengths are absorbed and which are transmitted through the material, resulting in the observed color.
When colors are absorbed the light changes into what?
When colors are absorbed, the light is converted into other forms of energy, such as heat or chemical energy. This absorption of light results in the color of the material appearing the way it does to our eyes.
If red light is absorbed what color is seen?
If red light is absorbed, the color seen will be the complementary color of red, which is cyan.
What is observed when white light strikes a block of charcoal?
When white light strikes a block of charcoal, the charcoal absorbs most of the light across the visible spectrum, reflecting very little back. This results in the block appearing black in color due to the absorption of all colors of light.
When zinc solution is burned what flame color is observed?
When a zinc solution is burned, a blue-green flame color is typically observed. This flame color is due to the presence of zinc in the solution, which emits specific wavelengths of light when heated.
What two wavelengths of light are most absorbed by the above pigment?
The pigment primarily absorbs green and red wavelengths of light, reflecting back other colors which results in its observed color.
What color is BTB in an acid?
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
What determine the color of a translucent material?
The color of a translucent material is determined by the wavelengths of light it absorbs and reflects. The material's molecular structure and composition play a key role in determining which wavelengths are absorbed and which are transmitted through the material, resulting in the observed color.
What color change does starch indicator solution make in the absence of starch?
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
How can you predict the absorption spectrum (opposite of emission spectrum) of a solution by looking at its color?
The absorption spectrum of a solution can be predicted by analyzing its color because the color we perceive is due to the wavelengths of light that are transmitted or reflected, rather than absorbed. For example, if a solution appears green, it primarily absorbs red and blue wavelengths of light, indicating that its absorption spectrum would show strong peaks in those regions. Thus, by identifying the color of the solution, one can infer which wavelengths are likely to be absorbed, leading to a corresponding prediction of the absorption spectrum.
What will you absorbed when blue litmus is introduced into a ferric chloride?
Blue litmus paper will turn red when introduced into a solution of ferric chloride. This change in color indicates that the solution is acidic.
Is ther evidence in results that light alone does not change the color of bromo blue solution?

What color wavelengths are absorbed during photosynthesis?
The green color is being absorbed
What is the color of light absorbed by an aqueous solution of copper sulphate?
An aqueous solution of copper sulfate absorbs light in the blue-green region of the spectrum. This is because copper ions in the solution absorb light of longer wavelength, leaving behind the blue-green color.
Why did you use different indicators for different pH solutions?
Different indicators are used for various pH solutions because they change color at specific pH ranges, allowing for accurate detection of acidity or alkalinity. Each indicator has a distinct transition range that corresponds to the pH of the solution being tested. By selecting the appropriate indicator, one can achieve more precise results in determining the pH level of the solution. This ensures that the color change observed reflects the actual pH of the solution.
