The wavelength of light is 529 nm. What is its wavelength in Å ?

Options

A. 529
B. 5.29
C. 5290
D. 52.9

Explanation

To convert the wavelength from nanometers (nm) to angstroms (Å), we can follow these steps:

### Step 1: Understand the conversion factor
We know that:
1 Å = 0.1 nm

### Step 2: Find the conversion from nm to Å
To convert nanometers to angstroms, we can rearrange the conversion factor:
1 nm = 10 Å

### Step 3: Calculate the wavelength in angstroms
Given the wavelength is 529 nm, we can convert it to angstroms using the conversion we found:
\[ \text{Wavelength in Å} = \text{Wavelength in nm} \times 10 \]
\[ \text{Wavelength in Å} = 529 \, \text{nm} \times 10 = 5290 \, \text{Å} \]

### Step 4: State the final answer
The wavelength of light in angstroms is 5290 Å.
