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.
What is the relationship between wavelength and absorbance in a spectrophotometry experiment?
In a spectrophotometry experiment, there is an inverse relationship between wavelength and absorbance. This means that as the wavelength of light increases, the absorbance decreases, and vice versa.
Is absorbance considered a discrete or continuous variable?
Absorbance is considered a continuous variable.
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 relationship between the wavelength of light and absorbance in a given substance?
The relationship between the wavelength of light and absorbance in a substance is that different substances absorb light at specific wavelengths. This absorption is measured as absorbance, which increases as the substance absorbs more light at its specific wavelength.
What is the relationship between absorbance and wavelength in spectroscopy?
Absorbance in spectroscopy is directly related to the wavelength of light being used. As the wavelength increases, the absorbance typically decreases. This relationship is important for determining the concentration of a substance in a sample based on the amount of light it absorbs at different wavelengths.
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.
