What causes change in a dependent variable?
The dependent variable is dependent on the independent variable, so when the independent variable changes, so does the dependent variable.
Positive correlation implies what--dependent variable improves as independent variable increases or dependent variable decreases as independent variable increases or?
dependent variable improves (or increases) as independent variable increases
What is the dependent and independent in a experiment?
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
What is meant by the dependent variable?
the dependent variable are the things that stay the same
Why is the output value called the dependent variable?
because it can change according to the independent variable. this dependent variable depends on the independent variable for its output. the independent variable is not affected by the dependent variable because the independent variable if found out first.
Can you explain the relationship between absorbance and wavelength in a graph?
In a graph, absorbance is typically shown on the y-axis and wavelength on the x-axis. The relationship between absorbance and wavelength is that as the wavelength of light increases, the absorbance generally decreases. This is because different substances absorb light at specific wavelengths, so the absorbance of a substance can vary depending on the wavelength of light being used.
In relation to spectroscopy what is the Optimum wavelength and how to find it?
The optimum wavelength is the wavelength by which the most light is absorbed by a substance. It can be found by finding the highest absorbance obtained when testing the substance's absorbance at various wavelengths. The wavelength that results in the greatest light absorbance is your optimum wavelength.
In an experiment the hypothesis is If the wavelength of the light shining on a plant is shortened the rate of photosynthesis is slowed down. If this experiment is performed the dependent variable . wi?
The dependent variable in this experiment would be the rate of photosynthesis. This is the variable that is being measured and is expected to change in response to the manipulation of the independent variable, which is the wavelength of light.
What is peak absorbance?
Peak absorbance refers to the wavelength at which a substance absorbs light most strongly. It is commonly used in spectrophotometry to determine the concentration of a substance in a solution by measuring the absorbance at its peak wavelength.
In an experiment the hypothesis is If the wavelength of the light shining on a plant is shortened the rate of photosynthesis is slowed down. If this experiment is performed the dependent variable?
The dependent variable in this experiment would be the rate of photosynthesis, as it is the outcome that is being measured and is expected to change based on the manipulation of the independent variable, which is the wavelength of the light.
How does the wavelength of light impact absorbance in a substance?
The wavelength of light affects absorbance in a substance because different substances absorb light at different wavelengths. When the wavelength of light matches the absorption peak of a substance, it is absorbed more strongly, leading to higher absorbance.
What is the name of the point at which wavelength independent pH and absorbance?
The isosbestic point is the name of the point at which a system displays wavelength-independent pH and absorbance.
Why do you use the wavelength with the maximum absorbance in spectroscop?
The wavelength with the maximum absorbance corresponds to the peak absorption of the compound being analyzed, providing the most accurate and precise measurement. By measuring absorbance at the maximum wavelength, we can ensure the highest sensitivity and specificity in detecting and quantifying the compound of interest.
What is the specific absorbance of aspirin?
The specific absorbance of a substance like aspirin refers to its unique ability to absorb light at a specific wavelength. To find the specific absorbance of aspirin, you would need to measure its absorbance at a specific wavelength using a spectrophotometer.
Why absorbance is decreased after maximum wavelength achieved?
After reaching maximum absorbance at a certain wavelength, further increase in wavelength leads to decreased absorbance because the molecules are not absorbing light at those wavelengths as efficiently. This decrease may be attributed to a shift in the electronic energy levels of the molecules, causing them to absorb less light as the wavelength increases beyond the maximum.
How does the relationship between wavelength and absorbance impact the absorption spectrum of a substance?
The relationship between wavelength and absorbance affects the absorption spectrum of a substance because different substances absorb light at specific wavelengths. As the wavelength of light changes, the absorbance of the substance also changes, resulting in a unique absorption spectrum that can be used to identify the substance.
What wavelength is the peak absorbance for cobalt chloride?
The peak absorbance for cobalt chloride typically occurs around 550-600 nm.
