Question #92976

Answer 1

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 × 10^-19` joule to `4.43 × 10^-19` joule

Explanation:

`E = hf`

`E_1 = 6.626 × 10^-34 Js× 606 × 10^12 Hz = 4.01 × 10^-19 J`

`E_2 = 6.626 × 10^-34 Js× 668 × 10^12 Hz = 4.43 × 10^-19 J`
