To determine the frequency of red light with a wavelength of 630 nm, we can use the equation that relates wavelength and frequency:
c = λ * f
Where: c is the speed of light in a vacuum (approximately 299,792,458 meters per second) λ is the wavelength in meters f is the frequency in hertz
First, let's convert the wavelength from nanometers to meters:
630 nm = 630 × 10^(-9) meters
Now, we can rearrange the equation to solve for frequency:
f = c / λ
Plugging in the values:
f = 299,792,458 m/s / (630 × 10^(-9) m)
Calculating this expression:
f ≈ 476,190,476,190.5 Hz
Therefore, the frequency of red light with a wavelength of 630 nm is approximately 476,190,476,190.5 hertz.
