The frequency of light can be calculated using the formula:
frequency = speed of light / wavelength
The speed of light is approximately 3.0 x 10^8 meters per second.
Given a wavelength of 700 x 10^-9 meters, we can substitute these values into the formula:
frequency = (3.0 x 10^8 m/s) / (700 x 10^-9 m)
Simplifying the expression:
frequency = (3.0 x 10^8 m/s) * (10^9 / 700)
frequency = 4.29 x 10^14 Hz
Therefore, the frequency of red light with a wavelength of 700 x 10^-9 meters is approximately 4.29 x 10^14 Hz.
