Kamila [148]

Answer:

$698 \ THz$

Explanation:

Data provided as per the question below:-

Wavelength = 430.nm

The computation of the frequency of the light is shown below:-

Frequency = Velocity of light ÷ Wavelength

The Velocity of light = $= {3.0 \times 10^8 \ m/s}$

Wavelength = 430 nm = $4.30 \times 10^-^7$ m

Frequency = $\frac{3.0 \times 10^8 \ m/s}{4.30 \times 10^-^7}$

$= 6.98 \times 10^1^4 \ hz$

$= 6.98 \times 10^2 \ Thz$

= $698 \ THz$

Therefore for determining the frequency we simply applied the above formula.
