Wavelength Of Light Determines The Color Of Light

Figure 22.8 illustrates the different colors of the visible spectrum of light and their wavelength ranges. Suppose the frequency of light a potassium compound emits is 7.41 x 10^{14} Hz. What color in the visible spectrum would you expect to see when the potassium compound is heated in a Bunsen burner flame?

**The strings**:
S_{7}P_{2}A_{21} (Identity - Physical Property)
**The math**:

Pj Problem of Interest is of type *identity* (physical property). *Identity* of color of emited light with a given frequency..

The equation that relates the frequency of light to its wavelength is as follows:

**ν = c/λ**

where ν is frequency of light, c is velocity of light (c = 3 x 10^{10} cm/sec) and λ is wavelength of light

So, 7.41 x 10^{14} = (3 x 10^{10})/λ

So, &lambda = (3 x 10^{10})/(7.41 x 10^{14}) = 4.05 x 10^{-5} cm

= (4.05 x 10^{-5})10^{8} = 4050 Å

Wavelenght of 4050 Å is within the violet region

So, expected color of light is violet.

Math

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
