Fascinating Fact about Light Wave Frequency

What is the frequency of a light wave with a wavelength of 7.0 x 10^-7 meters and traveling at a speed of 3.0 x 10^8 meters/second?

A. 2.5 x 10^-14 hertz B. 4.3 * 10^14 hertz C. 1.7 * 10^-14 hertz D. 5.1 x 10^-14 hertz

Answer: B = 4.3 * 10^14 hertz

The frequency of the light wave is 4.3 * 10^14 hertz. This is calculated using the formula: Frequency = Speed of light / Wavelength

Light is an electromagnetic wave that travels at a speed of 3.0 x 10^8 meters/second. When the wavelength of the light wave is 7.0 x 10^-7 meters, we can calculate the frequency using the formula mentioned earlier.

By substituting the values into the formula and performing the necessary calculations, we find that the frequency of the light wave is indeed 4.3 * 10^14 hertz. This shows the relationship between the speed of light, wavelength, and frequency in electromagnetic waves.
