Question
Hello I was wondering if you could please create an answer key with no work since the paper is asking us for both however I’d just like the answer key to see as a reference that my answers will be correct thank you so much sorry for the bother :)
![**Wavelength, Frequency, and Energy Worksheet**
**Directions:** Complete this worksheet on a separate piece of paper. Show all equations, work, units, and 3 significant figures for full credit. Below are equations and conversions that you may find useful.
\[C = \lambda \nu \]
\[E = h \nu = \frac{hc}{\lambda}\]
\[C = 3.00 \times 10^8 \, \text{m/s} \]
\[h = 6.626 \times 10^{-34} \, \text{J} \cdot \text{s} \]
\[1 \, \text{nm} = 10^{-9} \, \text{m} \]
