To find frequency or wavelength, use the wave speed equation, c = λ × f. Frequency and wavelength have an inverse relationship, and for light, c is always 3.00 x 10⁸ m/s. The equation can be rearranged to solve for either variable as needed in an example calculation.
To solve for frequency and wavelength, use the wave speed equation: c = λ × f, where c is the speed of light, λ (lambda) is the wavelength, and f is the frequency. The speed of light is a constant (≈ 3.00 × 10⁸ m/s), so you can rearrange the equation to solve for the desired variable. For example, if you have the wavelength (λ) of yellow light as 6.00 × 10⁻⁷ m, the frequency (f) is found by f = c/λ, giving f = (3.00 × 10⁸ m/s) / (6.00 × 10⁻⁷ m) which equates to 5.00 × 10ⁱ´ Hz.
In conclusion, wavelength and frequency have an inverse relationship, where longer wavelengths correspond to lower frequencies and shorter wavelengths correspond to higher frequencies. Use this relationship along with the wave speed equation for solving problems involving electromagnetic waves, such as light.
