For c = lv, the constant c is 3 x 108 m/s.  What is v if l is 4.681 micrometers

The equation you have is:

\[
c = l \cdot v
\]

where:
- \( c = 3 \times 10^8 \, \text{m/s} \) (the speed of light),
- \( l = 4.681 \, \mu m \) (wavelength),
- \( v \) is the frequency.

First, convert the wavelength \( l \) from micrometers to meters:

\[
4.681 \, \mu m = 4.681 \times 10^{-6} \, \text{m}
\]

Now, solve for \( v \):

\[
v = \frac{c}{l} = \frac{3 \times 10^8 \, \text{m/s}}{4.681 \times 10^{-6} \, \text{m}}
\]

Let's calculate the frequency \( v \).# Given values
c = 3 * 10**8  # speed of light in m/s
l = 4.681 * 10**-6  # wavelength in meters

# Calculate frequency v
v = c / l
vThe frequency \( v \) is approximately \( 6.41 \times 10^{13} \, \text{Hz} \) (hertz).
