The wavelength of red light is 800 nm. Find its frequency. Speed of light = `3 xx 10^(8) m s^(-1).

Text Solution

AI Generated Solution

To find the frequency of red light with a wavelength of 800 nm, we can use the formula that relates the speed of light (c), wavelength (λ), and frequency (ν): \[ \nu = \frac{c}{\lambda} \] ### Step 1: Convert Wavelength from Nanometers to Meters The given wavelength is in nanometers (nm), and we need to convert it to meters (m) for consistency with the speed of light. ...
