Answer:
6.25 × 10^14 Hz
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
