What are the flame test Colours?
dip a clean wire loop into a solid sample of the compound being tested. put the loop into the edge of the blue flame from a Bunsen burner. observe and record the flame colour produced….Flame tests.
| Ion present | Flame test colour |
|---|---|
| Sodium, Na + | Yellow |
| Potassium, K + | Lilac |
| Calcium, Ca 2+ | Orange-red |
| Barium, Ba 2+ | Green |
What do different color flames mean?
Hotter fires burn with more energy which are different colors than cooler fires. Although red usually means hot or danger, in fires it indicates cooler temperatures. While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames.
Does red light travel faster than green light?
So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy….Visible Spectrum.
| Color | Wavelength Range (nm) |
|---|---|
| Yellow | 570–590 |
| Green | 495–570 |
| Blue | 450–495 |
| Violet | 380–450 |
Which light travels faster in glass?
So according to equation (1) velocity of light is directly proportional to the wavelength. So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass.
Do all colors of light have the same energy?
All colors do not have the same energy. The blues and violets have the most energy. The reds and or- anges have the least energy.
Which color has the highest energy Why?
Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
What are the colors that have higher energy?
The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy.
