wavelength= speed / frequency

so.....3× 10^8 / 7.26×10^14
= .413× 10^(-6)

in scientific notation= 4.13×10^(-7)

in nanometer = 413 nm

The wavelength of violet light is 413 nm.

How do you calculate the wavelength?

Given that the violet light has a frequency of 7.26 × 10^14 Hz and travels at a speed of 3.00 × 10^8 m/s.

The wavelength can be defined as given below.

\(\lambda = \dfrac {v}{f}\)

Where \(\lambda\) is the wavelength of light, v is the speed and f is the frequency of the light. Substituting the values, we get the wavelength.

\(\lambda = \dfrac { 3\times 10^8}{7.26 \times 10^{14}}\)

\(\lambda = 4.13 \times 10^{-7}\;\rm m\)

In nanometers, the wavelength is,

\(\lambda = 413 \times 10^{-9} \;\rm m = 413 \;\rm nm\)

Hence the wavelength of the violet light is 413 nm.
