To find the frequency of violet light with a wavelength of 450 nm (nanometers), we can use the formula:
Frequency (f) = Speed of Light (c) / Wavelength (λ)
The speed of light (c) is approximately 299,792,458 meters per second (m/s) in a vacuum or air.
First, let's convert the wavelength from nanometers to meters:
450 nm = 450 × 10^(-9) meters
Now, we can calculate the frequency:
f = c / λ
f = 299,792,458 m/s / (450 × 10^(-9) meters)
Simplifying the expression:
f ≈ 6.66 × 10^14 Hz
Therefore, the frequency of violet light with a wavelength of 450 nm is approximately 6.66 × 10^14 Hz.
