How absorption spectrum is obtained?
An absorption spectrum is obtained by passing light through a material and measuring the amount of light absorbed at each wavelength. The absorption spectrum shows the absorption of light by the material at different wavelengths, providing information on the electronic structure and composition of the material. This technique is commonly used in various fields such as chemistry, physics, and biology to study the properties of different substances.
Which color on the electromagnetic spectrum has the shortest wavelength?
Violet light has the shortest wavelength on the electromagnetic spectrum.
What is the wavelength of a Red spectrum?
The wavelength of red light typically falls between 620 and 750 nanometers. It is on the longer end of the visible light spectrum.
What colour light has the lowest wavelength?
Violet light has the lowest wavelength in the visible light spectrum.
What has the second longest wavelength?
Red light has the second longest wavelength in the visible light spectrum, after infrared light.
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 is the longest wavelength and least energy in the visible spectrum?
The longest wavelength in the visible light spectrum is at the red end (at about 750nm) the lowest is violet (450nm). For a given intensity source the energy that can be generated is equal.The answer you are looking for is 720-680nm
The longest wavelength within the visible spectrum is what color light?
Red light has the longest wavelength within the visible spectrum.
Which color on the electromagnetic spectrum has the shortest wavelength?
Violet light has the shortest wavelength on the electromagnetic spectrum.
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.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
What is the wavelength of a Red spectrum?
The wavelength of red light typically falls between 620 and 750 nanometers. It is on the longer end of the visible light spectrum.
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
What colour light has the lowest wavelength?
Violet light has the lowest wavelength in the visible light spectrum.
Is a red light a visible light with the shortest wavelength?
No, red light has the longest wavelength within the visible light spectrum.
