The speed of light in a vacuum is approximately... - SS2 Physics Electromagnetic Waves Question
The speed of light in a vacuum is approximately 3 × 108 m/s. What is the wavelength of an electromagnetic wave with a frequency of 2 × 1015 Hz?
We can use the equation λ = c/f
Substituting the values, λ = (3 × 108 m/s)/(2 × 1015 Hz).
Simplifying the expression, λ = 1.5 × 10-7 m or 150 nm.
