QUESTION:
A krypton fluoride laser emits light at a wavelength of 248 nm. This is the same as:
(a) 0.0248 mm;
(b) 2.48 \(\mu m\);
(c) 0.248 \(\mu m\);
(d) 24,800 \(\mathring{A}\).
ANSWER:Step 1 of 2
Wavelength: \(\lambda=248 \mathrm{~nm}\)
Writing it in scientific notation:
\(\begin{array}{l}
\lambda=248 \times 10^{-9} \mathrm{~m} \\
\lambda=248 \times 10^{-3} \times 10^{-6} \mathrm{~m} \\
\lambda=0.248 \times 10^{-6}=0.248 \mu \mathrm{m}
\end{array}\)
