4. Calculate the wavelength (in nm) of light with a frequency of 6.05 x 104 Hz.

4.955x10¹²nm

Explanation:

It is possible to obtain wavelength from the frequency of a wave using the expression:

ν = C / λ

Where wavelength, ν, is given in m

Speed of light, C, is 2.998x10⁸m/s

And frequency, λ, is given in Hz = s⁻¹ = 6.05x10⁴s⁻¹

ν = C / λ

ν = 2.998x10⁸m/s / 6.05x10⁴s⁻¹

ν = 4955m

In nm:

4955m * (1x10⁹nm / 1m) =
