Violet light has a frequency of 7.26 × 1014 Hz and travels at a speed of 3.00 × 108 m/s. The wavelength of violet light, rounded to the nearest nanometer, is

Answer 1

For this question we can use the equation:

wavelength = velocity/frequency

Now plug the given values into the equation:

(3x10^8 m/s) / (7.26x10^14) = 4.312x10^-7 m

To convert this answer to nanometers (nm) we can multiply 4.312x10^-7 m by 1x10^9 to get the final answer:

413 nm
