Question #6914a
1 Answer
The wavelength of green light ranges from 492 nm to 597 nm. The frequency ranges from 520 THz to 609 THz.
Explanation:
Here's the spectrum of visible light.
(From www.christianklintholm.com)
The wavelength of green light ranges from 492 nm to 577 nm.
The formula relating frequency and wavelength is
#color(blue)(|bar(ul(color(white)(a/a) fλ=c color(white)(a/a)|)))" "#
where
We can rearrange the formula to get
#color(blue)(|bar(ul(color(white)(a/a) f = c/λcolor(white)(a/a)|)))" "#
We can use this formula to calculate the frequencies at each end of the wavelength range.
At 492 nm,
At 577 nm,
∴ The frequency of green light ranges from 520 THz to 609 THz.
