Q: The speed of a wave is a product of its wavelength and what else?


Read this paragraph and choose the correct option from the provided answers:

The speed of a wave is a product of its wavelength and frequency. Because the speed of electromagnetic waves through space is constant, the wavelength or frequency of an electromagnetic wave can be calculated if the other value is known.

 Choices:

- voltage

- density

- magnitude

- frequency


A:
frequency
