Final answer:
An electromagnetic wave transmits energy through space, characterized by its wavelength and frequency, moving at the constant speed of light (c).
Step-by-step explanation:
As an electromagnetic wave moves through space, it transfers energy from one region to another which is characterized by the wavelength and frequency of the wave. Electromagnetic waves, including light, travel through a vacuum at a constant speed, denoted by c, which is approximately 3.00 x 108 m/s. This radiation exhibits behavior similar to waves in that it can be characterized by its wavelength (λ or lambda) and frequency (ν or nu), using the relationship c = λ
u. The wavelength measures the distance between two consecutive crests or troughs of a wave, whereas the frequency measures how many waves pass a given point in one second. The energy of an electromagnetic wave is directly tied to its frequency, through Planck's law, as E = h
u, where h is Planck's constant.
