SUMMARY
The wavelength of red light with a frequency of 430 THz is calculated using the formula λ = c/f, where c is the speed of light (3 x 108 m/s) and f is the frequency. The correct calculation yields a wavelength of approximately 6.98 x 10-7 meters, or 698 nm. A common error in this calculation involves misplacing decimal points or powers of ten, which can lead to incorrect results.
