Question

Use Mathematical Representations

All electromagnetic waves travel at the same speed in a vacuum, usually referred to as the speed of light. This speed is approximately 300,000 kilometers per second and is represented by the symbol c.


4. Identify the formula you can use to calculate the speed of an electromagnetic wave.

Answer 1

Answer:The formula used to calculate the speed of an electromagnetic wave is:

v = λ * f

Where:

v represents the speed of the wave,

λ (lambda) represents the wavelength of the wave,

f represents the frequency of the wave.

However, in the context of the given information, it is already stated that the speed of all electromagnetic waves in a vacuum is approximately 300,000 kilometers per second, represented by the symbol c. Therefore, the formula becomes:

c = λ * f

In this case, c represents the speed of light in a vacuum, λ represents the wavelength of the electromagnetic wave, and f represents the frequency of the wave.
