Answer: It’s 6.88 * 10 ^14
Explanation: this is the right answer for a pex
Answer:
462nm
Explanation:
E=hf
c=fλ
E=hc/λ
The relation between the wavelength λ of a photon and its energy E is following: E=hc/λ where h = 6.626×10⁻³⁴ J⋅s is Planck’s constant, c = 3×10⁸ m/s is the speed of light. If E = 4.56×10^⁻¹⁹ J then λ = 463nm(nano meter)
