Step-by-Step

1. Wavelength from c = fλ

λ=cf=2.998×1084.74×1014=6.325×10−7 m\lambda = \frac{c}{f} = \frac{2.998 \times 10^{8}}{4.74 \times 10^{14}} = 6.325 \times 10^{-7} \text{ m}

2. Photon energy from E = hf

E=hf=(6.626×10−34)(4.74×1014)=3.141×10−19 J=1.961 eVE = hf = (6.626 \times 10^{-34})(4.74 \times 10^{14}) = 3.141 \times 10^{-19} \text{ J} = 1.961 \text{ eV}

4. Wien's displacement law

λmax=bT=2.898×10−35778=5.016×10−7 m\lambda_{\text{max}} = \frac{b}{T} = \frac{2.898 \times 10^{-3}}{5778} = 5.016 \times 10^{-7} \text{ m}
