Final answer:
The frequency of light with a wavelength of 1520nm is calculated using the speed of light and is approximately 1.97 × 1014 hertz (Hz).
Step-by-step explanation:
The question asks about the frequency of light with a wavelength of 1520nm. To calculate this, we use the equation for the speed of light, c = λf, where c is the speed of light in a vacuum, λ (lambda) is the wavelength, and f is the frequency. The speed of light (c) is a constant that is approximately 3.0 × 108 m/s. Since we have the wavelength in nanometers (nm), we must first convert that to meters by recognizing that 1 nm = 1 × 10-9 m.
A wavelength of 1520 nm is therefore 1520 × 10-9 m. We can now rearrange the equation to solve for frequency (f):
f = ÷
Inserting the values we have:
f = ÷ = (3.0 × 108 m/s) / (1520 × 10-9 m) ≈ 1.97 × 1014 Hz
The frequency of light with a wavelength of 1520nm is approximately 1.97 × 1014 hertz (Hz).
