Frequency of blue light ranges from 606 THz to 668 THz

Energy of a single photon of blue light will be in the range of $4.01 \times 10^{- 19}$ $4.01 × 10^-19$ joule to $4.43 \times 10^{- 19}$ $4.43 × 10^-19$ joule

Explanation:

$E = h f$ $E = hf$

$E_{1} = 6.626 \times 10^{- 34} J s \times 606 \times 10^{12} H z = 4.01 \times 10^{- 19} J$ $E_1 = 6.626 × 10^-34 Js× 606 × 10^12 Hz = 4.01 × 10^-19 J$

$E_{2} = 6.626 \times 10^{- 34} J s \times 668 \times 10^{12} H z = 4.43 \times 10^{- 19} J$ $E_2 = 6.626 × 10^-34 Js× 668 × 10^12 Hz = 4.43 × 10^-19 J$
