The rainbow of visible colors in the electromagnetic spectrum varies continuously from the longest wavelengths (the reddest colors) to the shortest wavelengths (the deepest violet colors) our eyes can detect. wavelengths near 655 nm are perceived as red. those near 515 nm are green and those near 475 nm are blue. calculate the frequency of light (in hz) with a wavelength of 655 nm, 515 nm, and 475 nm.

Explanation:

We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as where v is speed of light is frequency of light is wavelength of light

In first case we have given λ=655 nm

so using formula  

Hz

In second case we have wavelength 515 nm so by using above formula

In third case we have wavelength 475 nm

so

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
