The frequency of light can be calculated using the formula:
f = c / λ
Where: f is the frequency of light, c is the speed of light (approximately 3 x 10^8 meters per second), λ is the wavelength of light.
To find the frequency of blue light with a wavelength of 450 nm (nanometers), we first need to convert the wavelength to meters:
450 nm = 450 x 10^(-9) meters
Now we can substitute the values into the formula:
f = (3 x 10^8 m/s) / (450 x 10^(-9) m)
Simplifying this expression:
f ≈ 6.67 x 10^14 Hz
Therefore, blue light with a wavelength of 450 nm has a frequency of approximately 6.67 x 10^14 Hz.
