Module 1, Assignment 1
Describe the light sources and spectra that you have projected in detail as well as any experimental difficulties you encountered in the process. How do the different light sources compare with each other?

No matter what light source you looked into, the only colors you would see are the colors you would see on the rainbow. The colors include red, purple, green, blue, yellow, and orange. But I also figured that the stronger the light source, the more colors of the spectra you can notice. And the dimmer the light source, the less colors you can see.
ReplyDeleteWell, at least that's how it was for me.
I learned that information about stars is discovered based on the spectrum. There are three different main spectra called Continuum, Emission of Line, and Continuum Spectrum with absorption lines. They show different patterns. Continuum Spectrum would have a column of all the colors (lights). The Emission Line would have only a few colors appear. I think those colors is what would be called wavelengths. They both are produced by hot objects but differ by its density and gasses that is present. Continuum with absorption lines is the opposite of what an Emission line would appear. It would be like the Continuum but this time a few wavelength would be missing known as “absorption”.
ReplyDeleteMost lights inside of my house seem to be the same—continuum spectrum. The chart on the spectroscope has the letter “a” underneath the spectrum that looks like a continuum and it says that the lamp spectrum is incandescent. Reading the list of different lamp spectra is confusing because I don’t know what “incandescent” is. Sometimes it is difficult to capture the spectra with my camera through the spectroscope so I would need to repeat the pictures until I get a good spectrum. I have not found a continuum absorption or emission spectra. I also tried finding the spectra during the day outside (on a cloudy and sunny day). It all the colors still appeared. I thought that on the sunny day the spectra would lose some colors because of the heat but it didn't.
Assignment 1
ReplyDeleteIncandescent light bulb: full rainbow
Frosted bulb: full rainbow, but blurred
Blue coating: all colors shown, but much more blue and purple
Green coating: all colors shown, but much more green
Helium: blue, green, yellow, red
Krypton: blue, green, orange, red
Neon: red, orange, yellow, green, blue
Hydrogen: red, green, purple
Mercury: blue, green, orange, red
Fluorescent bulb: same as mercury: blue, green, orange, red
Red LED: just red
White LED: full rainbow
Incandescent bulb- Showing a rainbow spectrum
ReplyDeleteBlue: I think you will see less of a range of colors. Just plain blue, red, and green. Thick Line.
Blue: It has all the same colors but a much thinner line.
Green Vs. Blue: More red in the green bulb and more blues and purple in the blue bulb.
Helium Bulb: You see straight lines, they aren't individual lines. The bulb copied four times in different colors. Red, yellow, green, blue.
Krypton Bulb: I see green and orange lines in two straight lines and faint likes of blue and red on ether side. And green on either side.
Neon Bulb: Very red,orange, yellow, and a little green. Very little blue.
Hydrogen Bulb: Red, turquoise, purple, and a little yellow.
Mercury Bulb: Blue, green, orange, and some red.
Curly light bulb vs. Mercury Bulb: They are the same thing. They both have mercury. Curly light bulb looks white because of a coating on the bulb. In signs also.
Red LED: Only red light, short red thin line.
White LED: Really think line of every color.

ReplyDeleteBulbs
Incandescent bulb: its a Full Rainbow
Frost Bulb: Full Rainbow (blurry)
Blue light: all colours and a thin line scale
Green light: all colours but more green scale
Helium: Blue, green, orange, red emission lines
Krypton: Blue, green, orange, red
Neon: green, orange, red, yellow, blue
Hydrogen: Blue, turquoise, red
Mercury: Blue, green, orange, red
Florescent bulb: has the same blue, green, orange, red
Red Led: Red
White Led: all colours
Sun: all colours (really bright)
Incandescent bulb-full rainbow spectrum.
ReplyDeleteFrosty incandescent bulb: the same colors as a regular incandescent bulb but the line is thinner.
Green Incandescent bulb vs. Blue Incandescent bulb: More red in the green bulb and more blue in and purple in the blue bulb.
Helium bulb: 4 emission lines: red, yellow, green, blue.
Krypton bulb: 4 emission lines: green, orange, blue and red.
Neon bulb: 5 emission lines: red, orange, yellow, green and a faint blue.
Hydrogen bulb: 4 emission lines: red, turquoise, purple and faint yellow.
Mercury bulb: 4 emission lines: blue, green, orange and red.
Curly light bulb vs. Mercury bulb: they are the same because the curly light bulb has mercury in it. The curly light bulb looks white because of a coating on the bulb.
Red LED light: only red light, thing red line.
White LED light: Very thin line of the full spectrum.
