Final answer:
The SI unit of frequency, 'hertz,' is named after Heinrich Hertz, who confirmed the existence of electromagnetic waves and demonstrated that they travel at the speed of light.
Step-by-step explanation:
The SI unit of frequency is named after Heinrich Hertz, the German physicist who confirmed the existence of electromagnetic waves and proved that they travel at the speed of light. The unit hertz (1 Hz) is equivalent to one cycle per second.
Hertz's groundbreaking work included studies of the reflection, refraction, and interference patterns of electromagnetic waves, which allowed him to calculate their speed using the relationship v = fλ (velocity equals frequency times wavelength).
The SI unit of frequency is named after Heinrich Hertz, the German physicist who proved the existence of electromagnetic waves.
Hertz conducted a series of experiments in the late 19th century that confirmed the wave character of these waves and demonstrated that they travel at the speed of light. In his honor, the unit of frequency is called the hertz (Hz), where 1 Hz = 1 cycle per second.
