Why are there gaps in the emission spectra?
An emission spectrum consists of all the radiations emitted by atoms or molecules, whereas in an absorption spectrum, portions of a continuous spectrum (light containing all wavelengths) are missing because they have been absorbed by the medium through which the light has passed; the missing wavelengths appear as dark …
What do the lines in an emission spectrum represent?
What do the individual lines in a bright line emission spectrum represent? They represent the wavelengths of light that is absorbed by the spectrum They represent the energy that the atom gives off when their electrons are in place. They also represent frequency and energy.
What do the lines on the emission spectra correlate with?
Emission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. When light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands.
What are the dark gaps in the solar spectrum?
Dark gaps in the spectrum, called Fraunhofer absorption lines, represent absorption by atoms or ions in the Sun. The wavelengths of these absorption lines can be used to identify the elements in the Sun, and the relative darkness of the lines helps establish the relative abundance of these elements.
What is the strongest line in the solar spectrum?
The visible and infrared spectrum of the photosphere shows absorption lines, known as the Fraunhofer spectrum. The strongest of these lines are produced by H, Mg, Fe, Ca, and Si, as well as singly ionized Ca and Mg.
What color is the highest frequency?
Violet waves
Which color has the highest energy Why?
violet
What are the color that have higher energy than red?
Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.
Which color has the most energy in Roygbiv?
Violet Carries the Highest Energy Among ROYGBIV Colors The energy of a wave such as light is directly proportional to its frequency. In addition, violet has the shortest wavelength among the ROYGBIV colors.
Which has more energy red light or green light?
So, higher the frequency, higher the energy. Hence, green light has more energy than red light.
Is blue or red light faster?
Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light.
Does red light travel faster than blue light in glass?
So from the analogy above, slower speeds in the glass make the light bend more. Blue light travels slightly slower in glass than red light, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light.
Does red light travel faster in water?
Why is red light faster than blue light? In air, glass, water and many other transparent materials, red light travels faster than blue light.
How fast do red light travel in a vacuum?
Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).
Does red light travel faster than violet in glass?
Also, we know that the refractive index of the medium is inversely proportional to the speed of light. Therefore, the speed of red light will be greater than the violet. Therefore, in glass the red light will travel faster than the violet light.
