An acrostic for the em spectrum?
GaXrUlViInMiRa. Done by the first two letters of each type of wavelength. The visible spectrum really consist of the colors but here is listed as "Vi." Gallant X-rays ultimately violate interesting micron radios.
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
The wavelength of the photon emitted can be calculated using the Rydberg formula: 1/wavelength = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant, n1 is the initial energy level (2 in this case), and n2 is the final energy level (1 in this case). Plugging in the values gives the wavelength of the photon emitted.
What is derivative spectroscopy?
A spectrum that is the result of applying a derivative transform to the data of the original spectrum. Derivatives of spectra are very useful for two reasons: 1. First, and second derivatives may swing with greater amplitude than the primary spectra. For example, a spectrum suddenly changes from a positive slope to a negative slope, such as at the peak of a narrow feature (see the figure below). The more distinguishable derivatives are especially useful for separating out peaks of overlapping bands. 2. In some cases derivative spectra can be a good noise filter since changes in base line have negligible effect on derivatives. For example, scattering increases with wavelength for some biologically active macromolecules causing an increasing slope of the absorbance baseline. A commonly used approximation of the first derivative is: dα/dλ = [α (λ + Δλ) - α (λ - Δλ)] / 2Δλ. A more accurate approximation of the first and higher order derivatives is presented in thorough explanations by Whitaker1 and Morrey2. Still other methods involve a best fit match to the curve on the features of interest and performing higher order derivatives with numerical analysis. Derivative spectra yield good signal-to-noise ratios only if the difference of noise levels at the endpoints of the interval is small enough to yield a noise equivalent Δdα/dλ calculation much smaller than the absorbance.
Who first attached a spectroscope to a telescope to study the spectrum of stars?
Hubble
What is the reason of naming helium?
The first evidence of helium was observed on August 18, 1868 as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun. The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India.the element with the Greek word, helios, for the Sun.
What is the wavelength of two waves when the first wave has twice the frequency of the second?
The first has half the wavelength of the second
Why it is important to first obtain the absorption spectrum of the soft drink before making a calibration?
to determine the wavelength of maximum absorption
What is the speed of a wave with a wavelength of MM and a frequency of Hz?
The speed of a wave is equal to the product of its wavelength and its frequency. (If you want to have the speed in meters/second, convert the wavelength to meters first.)
What does red mean in a rainbow?
Red is the color that appears first in a rainbow, on the outermost arc. It has the longest wavelength of all the colors in the visible light spectrum.
How does a wavelength of a sound increase decrease or stay the same as a musician changes from the first to second sound?
As a musician changes from the first to second sound, the wavelength of the sound can increase, decrease, or stay the same depending on factors such as the frequency of the sound, the instrument being used, and the musician's technique. A higher frequency sound will have a shorter wavelength, while a lower frequency sound will have a longer wavelength.
Is the first reading for blood pressure accurate or a second reading is better?
Second
The first color lost in the spectrum upon descent during a dive is?
Red because it has the shortest wavelength. Then you lose orange, green,blue, violet.
Does red light have a longer wavelength then blue because it's the first colour in the rainbow?
Yes, red light has a longer wavelength than blue light. In the visible light spectrum, red light has a longer wavelength and lower frequency compared to blue light. This difference in wavelength is due to how light waves interact with various materials and how they are diffracted within the atmosphere.
What is the frequency of Ne if wavelength 14.160 angstrom?
I assume you are talking about an electromagnetic wave; in this case, divide the speed of light (300,000,000 meters per second) by the wavelength. You must first convert the wavelength to meters (divide Angstrom by 1010).
Why does red have a lower frequency then other colors?
Red light has a lower frequency because it has a longer wavelength compared to other colors in the visible spectrum. Electromagnetic waves with longer wavelengths have lower frequencies, while waves with shorter wavelengths have higher frequencies. This is why red light, with its longer wavelength, falls on the lower end of the visible light spectrum in terms of frequency.
