What do the various colors displayed in the flame of a burning log indicate?

What do the various colors displayed in the flame of a burning log indicate? The colors of the flames indicate the types of atoms that are emitting light in the flame. A spectroscope displays the spectrum of light as brightness versus wavelength. When a gas glows, discrete colors are emitted.

Why do different atoms give off different colors of light?

Explanation: When atoms are heated, electrons will move from their ground state (lower energy level) to a higher energy level. The photons will have different wavelengths and frequencies, this makes photons of different energies produce different colors of light.

Which of these colors of light has the most energy per photon quizlet?

– Light waves carry more energy if their crests are closer together (higher frequency and shorter wavelength). – Violet light (shorter wavelength) carries more energy per photon than red light (longer wavelength).

What part of the electromagnetic spectrum is most absorbed by water?

-infrared
The vibrational transition of water which can be found in the near and mid-infrared basically is the most absorbed by water.

What colors are in fire?

Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.

Which elements give off which colors?

Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame.

Which color of visible light has the most energy per photon?

violet light
Since the energy of a photon is directly proportional to the frequency of the light, the light having the greatest frequency will have the greatest energy per photon. Therefore, the violet light will have the greatest energy per photon.

Which has more energy per photon red or blue?

Shorter waves vibrate at higher frequencies and have higher energies. Red light has a frequency around 430 terahertz, while blue’s frequency is closer to 750 terahertz. Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits about 3.1 eV.

What color is most absorbed by water?

blue
“The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue.”

Why is water greenish blue cyan?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

What makes the colors in a burning log?

The variety of colors seen in a burning log come from the variety of A. multi-layered incandescent surfaces. B. electron transitions in various atoms. C. temperatures. D. chemicals in the log. E. absorbing gases between the log and the viewer.

What kind of wood do you use to start a fire?

Once a fire is established and there is some heat in the base of the fire, it should be fuelled with hardwood to maintain a slow burning fire with a good heat output. Softwood can produce a very pleasing flame to look at but it will burn very quickly and you will get through a large volume of wood in a very short time.

Which is the best wood for a fire lighter?

Burns well but has a tendency to spark. Birch burns easily and can be burnt unseasoned. It also burns very quickly so is often best mixed with a slower burning wood such as Oak or Elm. Birch bark can make an excellent fire-lighter.
