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 nm.

c=λν

3*10^8 m/s * 10^9 nm/m / 7.26*10^14 s^-1= λ

=413.22 nm

λ=413 nm

Answer : The wavelength of violet light is, 413 nm

Explanation :

Formula used :

where,

= frequency of violet light =

As we know that,

= wavelength of violet light

c = speed of light =

Now put all the given values in the above formula, we get:

conversion used :

Therefore, the wavelength of violet light is, 413 nm
