Answer:

6.25 × 10^14 Hz

Step-by-step explanation:

  • The relationship between frequency and wavelength is given by the equation;
  • Velocity = Frequency × wavelength

In this case, the velocity of light is 2.998 × 10^8 m/s

Wavelength = 480 nm

But; 1 nm = 10^-9 M

Therefore,

480 nm = 4.8 × 10^-7 M

Rearranging the formula;

Frequency = Velocity ÷ wavelength

= (2.998 × 10^8 m/s) ÷ 4.8 × 10^-7 m)

= 6.246 × 10^14 Hz

= 6.25× 10^14 Hz

Therefore, the frequency of the blue light photon is 6.25 × 10^14 Hz
