To calculate the frequency of light given its wavelength, you can use the formula:
frequency = speed of light / wavelength
The speed of light is approximately 3.00 x 10^8 meters per second (m/s).
First, let's convert the wavelength from nanometers (nm) to meters (m):
6.5 x 10^-7 nm = 6.5 x 10^-7 × 10^-9 m = 6.5 x 10^-16 m
Now we can calculate the frequency:
frequency = (3.00 x 10^8 m/s) / (6.5 x 10^-16 m) ≈ 4.62 x 10^23 Hz
Therefore, the frequency of light with a wavelength of 6.5 x 10^-7 nm is approximately 4.62 x 10^23 Hz.
