Which one of the following corresponds to a photon of highest energy?
- A \(\lambda=300 \mathrm{mm}\)
- B \(v=3 \times 10^{4} \mathrm{s}^{-1}\)
- C \(\bar{v}=30 \mathrm{cm}^{-1}\)
- D \(\varepsilon=6.626 \times 10^{-27} \mathrm{J}\)
Answer & Solution
Correct Answer
(A) \(\lambda=300 \mathrm{mm}\)
Step-by-step Solution
Detailed explanation
\(\because E=h v=\frac{h c}{\lambda}=h c \cdot \bar{v} \quad\left(\because \frac{1}{\lambda}=\bar{v}\right)\) where \(E=\) energy of photon \(c=\) velocity of photon (-light) \(\lambda=\) wavelength of photon \(h=\) plank's constant. \(\therefore\) For \((\mathrm{a})\)…
