Question

Frequency (y) varies inversely with wavelength (x). Find the frequency (measured in THz ) of blue light if its k value is 175,720 and its wavelength is 230 meters. (Round to nearest whole number if necessary)

Answer 1

We have been that frequency (y) varies inversely with wavelength (x).

We know that two inversely proportional quantities are in form
`a=(k)/(b)`, where a is inversely proportional to b and k is constant of variation.

Our required equation would be
`y=(k)/(x)`.

To find frequency of blue light, we will substitute
`k=175,720` and
`x=230` in our equation as:

`y=(175,720)/(230)`

`y=764`

Therefore, the frequency of blue light is 764.
