If the wavelength of light is given as 3 units (such as meters), you can use the same formula as before to find the frequency:
c = λν
Where: c is the speed of light in a vacuum (approximately 3.00 x 10^8 m/s) λ is the wavelength in meters ν is the frequency in hertz (Hz)
Now, you can rearrange the formula to solve for the frequency:
ν = c / λ
Substituting the values:
ν = (3.00 x 10^8 m/s) / 3 m
Calculating the frequency:
ν = 1.00 x 10^8 Hz
Therefore, if the wavelength of light is 3 units, the frequency would be 1.00 x 10^8 Hz.
